// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
//                   Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// Unit Tests      - http://benalman.com/code/projects/jquery-bbq/unit/
// 
// About: Release History
// 
// 1.3pre - (8/26/2010) Integrated <jQuery hashchange event> v1.3, which adds
//         document.title and document.domain support in IE6/7, BlackBerry
//         support, better Iframe hiding for accessibility reasons, and the new
//         <jQuery.fn.hashchange> "shortcut" method. Added the
//         <jQuery.param.sorted> method which reduces the possibility of
//         extraneous hashchange event triggering. Added the
//         <jQuery.param.fragment.ajaxCrawlable> method which can be used to
//         enable Google "AJAX Crawlable mode."
// 1.2.1 - (2/17/2010) Actually fixed the stale window.location Safari bug from
//         <jQuery hashchange event> in BBQ, which was the main reason for the
//         previous release!
// 1.2   - (2/16/2010) Integrated <jQuery hashchange event> v1.2, which fixes a
//         Safari bug, the event can now be bound before DOM ready, and IE6/7
//         page should no longer scroll when the event is first bound. Also
//         added the <jQuery.param.fragment.noEscape> method, and reworked the
//         <hashchange event (BBQ)> internal "add" method to be compatible with
//         changes made to the jQuery 1.4.2 special events API.
// 1.1.1 - (1/22/2010) Integrated <jQuery hashchange event> v1.1, which fixes an
//         obscure IE8 EmulateIE7 meta tag compatibility mode bug.
// 1.1   - (1/9/2010) Broke out the jQuery BBQ event.special <hashchange event>
//         functionality into a separate plugin for users who want just the
//         basic event & back button support, without all the extra awesomeness
//         that BBQ provides. This plugin will be included as part of jQuery BBQ,
//         but also be available separately. See <jQuery hashchange event>
//         plugin for more information. Also added the <jQuery.bbq.removeState>
//         method and added additional <jQuery.deparam> examples.
// 1.0.3 - (12/2/2009) Fixed an issue in IE 6 where location.search and
//         location.hash would report incorrectly if the hash contained the ?
//         character. Also <jQuery.param.querystring> and <jQuery.param.fragment>
//         will no longer parse params out of a URL that doesn't contain ? or #,
//         respectively.
// 1.0.2 - (10/10/2009) Fixed an issue in IE 6/7 where the hidden IFRAME caused
//         a "This page contains both secure and nonsecure items." warning when
//         used on an https:// page.
// 1.0.1 - (10/7/2009) Fixed an issue in IE 8. Since both "IE7" and "IE8
//         Compatibility View" modes erroneously report that the browser
//         supports the native window.onhashchange event, a slightly more
//         robust test needed to be added.

  // 
  // Adds a 'state' into the browser history at the current position, setting
  // location.hash and triggering any bound <hashchange event> callbacks
  // (provided the new state is different than the previous state).
  // 
  // If no arguments are passed, an empty state is created, which is just a
  // shortcut for jQuery.bbq.pushState( {}, 2 ).
  // 
  // Usage:
  // 
  // > jQuery.bbq.pushState( [ params [, merge_mode ] ] );
  // 
  // Arguments:
  // 
  //  params - (String) A serialized params string or a hash string beginning
  //    with # to merge into location.hash.
  //  params - (Object) A params object to merge into location.hash.
  //  merge_mode - (Number) Merge behavior defaults to 0 if merge_mode is not
  //    specified (unless a hash string beginning with # is specified, in which
  //    case merge behavior defaults to 2), and is as-follows:
  // 
  //    * 0: params in the params argument will override any params in the
  //         current state.
  //    * 1: any params in the current state will override params in the params
  //         argument.
  //    * 2: params argument will completely replace current state.
  // 
  // Returns:
  // 
  //  Nothing.
  // 
  // Additional Notes:
  // 
  //  * Setting an empty state may cause the browser to scroll.

  // 
  // Returns:
  // 
  //  (Anything) If key is passed, returns the value corresponding with that key

  // Event: hashchange event (BBQ)
  // 
  // Usage in jQuery 1.4 and newer:
  // 
  // In jQuery 1.4 and newer, the event object passed into any hashchange event
  // callback is augmented with a copy of the location.hash fragment at the time
  // the event was triggered as its event.fragment property. In addition, the
  // event.getState method operates on this property (instead of location.hash)
  // which allows this fragment-as-a-state to be referenced later, even after
  // window.location may have changed.
  // 
  // Note that event.fragment and event.getState are not defined according to
  // W3C (or any other) specification, but will still be available whether or
  // not the hashchange event exists natively in the browser, because of the
  // utility they provide.
  // 
  // The event.fragment property contains the output of <jQuery.param.fragment>
  // and the event.getState method is equivalent to the <jQuery.bbq.getState>
  // method.
  // 
  // > $(window).bind( 'hashchange', function( event ) {
  // >   var hash_str = event.fragment,
  // >     param_obj = event.getState(),
  // >     param_val = event.getState( 'param_name' ),
  // >     param_val_coerced = event.getState( 'param_name', true );
  // >   ...
  // > });
  // 
  // Usage in jQuery 1.3.2:
  // 
  // In jQuery 1.3.2, the event object cannot to be augmented as in jQuery 1.4+,
  // so the fragment state isn't bound to the event object and must instead be
  // parsed using the <jQuery.param.fragment> and <jQuery.bbq.getState> methods.
  // 
  // > $(window).bind( 'hashchange', function( event ) {
  // >   var hash_str = $.param.fragment(),
  // >     param_obj = $.bbq.getState(),
  // >     param_val = $.bbq.getState( 'param_name' ),
  // >     param_val_coerced = $.bbq.getState( 'param_name', true );
  // >   ...
  // > });
  // 
  // Additional Notes:
  // 
  // * Due to changes in the special events API, jQuery BBQ v1.2 or newer is
  //   required to enable the augmented event object in jQuery 1.4.2 and newer.
  // * See <jQuery hashchange event> for more detailed information.

// 
// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
//                   Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// Unit Tests      - http://benalman.com/code/projects/jquery-hashchange/unit/
// 
// About: Known issues
// 
// While this jQuery hashchange event implementation is quite stable and
// robust, there are a few unfortunate browser bugs surrounding expected
// hashchange event-based behaviors, independent of any JavaScript
// window.onhashchange abstraction. See the following examples for more
// information:
// 
// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
// 
// Also note that should a browser natively support the window.onhashchange 
// event, but not report that it does, the fallback polling loop will be used.
// 
// About: Release History
// 
// 1.3   - (7/21/2010) Reorganized IE6/7 Iframe code to make it more
//         "removable" for mobile-only development. Added IE6/7 document.title
//         support. Attempted to make Iframe as hidden as possible by using
//         techniques from http://www.paciellogroup.com/blog/?p=604. Added 
//         support for the "shortcut" format $(window).hashchange( fn ) and
//         $(window).hashchange() like jQuery provides for built-in events.
//         Renamed jQuery.hashchangeDelay to <jQuery.fn.hashchange.delay> and
//         lowered its default value to 50. Added <jQuery.fn.hashchange.domain>
//         and <jQuery.fn.hashchange.src> properties plus document-domain.html
//         file to address access denied issues when setting document.domain in
//         IE6/7.
// 1.2   - (2/11/2010) Fixed a bug where coming back to a page using this plugin
//         from a page on another domain would cause an error in Safari 4. Also,
//         IE6/7 Iframe is now inserted after the body (this actually works),
//         which prevents the page from scrolling when the event is first bound.
//         Event can also now be bound before DOM ready, but it won't be usable
//         before then in IE6/7.
// 1.1   - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
//         where browser version is incorrectly reported as 8.0, despite
//         inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
// 1.0   - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
//         window.onhashchange functionality into a separate plugin for users
//         who want just the basic event & back button support, without all the
//         extra awesomeness that BBQ provides. This plugin will be included as
//         part of jQuery BBQ, but also be available separately.

(function($,window,undefined){
  '$:nomunge'; // Used by YUI compressor.
  
  // Reused string.

    // Method / object references.

    fake_onhashchange,
    special = $.event.special,
    
    // Does the browser support window.onhashchange? Note that IE8 running in
    // IE7 compatibility mode reports true for 'onhashchange' in window, even
    // though the event isn't supported, so also test document.documentMode.
    doc_mode = doc.documentMode,
    supports_onhashchange = 'on' + str_hashchange in window && ( doc_mode === undefined || doc_mode > 7 );

  // leading #. Thanks for making this necessary, Firefox!
  function get_fragment( url ) {
    url = url || location.href;
    return '#' + url.replace( /^[^#]*#?(.*)$/, '$1' );
  };
  
  // Method: jQuery.fn.hashchange
  // 
  // Bind a handler to the window.onhashchange event or trigger all bound
  // window.onhashchange event handlers. This behavior is consistent with
  // jQuery's built-in event handlers.
  // 
  // Usage:
  // 
  // > jQuery(window).hashchange( [ handler ] );
  // 
  // Arguments:
  // 
  //  handler - (Function) Optional handler to be bound to the hashchange
  //    event. This is a "shortcut" for the more verbose form:
  //    jQuery(window).bind( 'hashchange', handler ). If handler is omitted,
  //    all bound window.onhashchange event handlers will be triggered. This
  //    is a shortcut for the more verbose
  //    jQuery(window).trigger( 'hashchange' ). These forms are described in
  //    the <hashchange event> section.
  // 
  // Returns:
  // 
  //  (jQuery) The initial jQuery collection of elements.
  
  // Allow the "shortcut" format $(elem).hashchange( fn ) for binding and
  // $(elem).hashchange() for triggering, like jQuery does for built-in events.

    return fn ? this.bind( str_hashchange, fn ) : this.trigger( str_hashchange );
  };
  
  // Property: jQuery.fn.hashchange.delay
  // 
  // The numeric interval (in milliseconds) at which the <hashchange event>
  // polling loop executes. Defaults to 50.
  
  // Property: jQuery.fn.hashchange.domain
  // 
  // If you're setting document.domain in your JavaScript, and you want hash
  // history to work in IE6/7, not only must this property be set, but you must
  // also set document.domain BEFORE jQuery is loaded into the page. This
  // property is only applicable if you are supporting IE6/7 (or IE8 operating
  // in "IE7 compatibility" mode).
  // 
  // In addition, the <jQuery.fn.hashchange.src> property must be set to the
  // path of the included "document-domain.html" file, which can be renamed or
  // modified if necessary (note that the document.domain specified must be the
  // same in both your main JavaScript as well as in this file).
  // 
  // Usage:
  // 
  // jQuery.fn.hashchange.domain = document.domain;
  
  // Property: jQuery.fn.hashchange.src
  // 
  // If, for some reason, you need to specify an Iframe src file (for example,
  // when setting document.domain as in <jQuery.fn.hashchange.domain>), you can
  // do so using this property. Note that when using this property, history
  // won't be recorded in IE6/7 until the Iframe src file loads. This property
  // is only applicable if you are supporting IE6/7 (or IE8 operating in "IE7
  // compatibility" mode).
  // 
  // Usage:
  // 
  // jQuery.fn.hashchange.src = 'path/to/file.html';

  /*
  $.fn[ str_hashchange ].domain = null;

  */
  
  // Event: hashchange event
  // 
  // Fired when location.hash changes. In browsers that support it, the native
  // HTML5 window.onhashchange event is used, otherwise a polling loop is
  // initialized, running every <jQuery.fn.hashchange.delay> milliseconds to
  // see if the hash has changed. In IE6/7 (and IE8 operating in "IE7
  // compatibility" mode), a hidden Iframe is created to allow the back button
  // and hash-based history to work.
  // 
  // Usage as described in <jQuery.fn.hashchange>:
  // 
  // > // Bind an event handler.
  // > jQuery(window).hashchange( function(e) {
  // >   var hash = location.hash;
  // >   ...
  // > });
  // > 
  // > // Manually trigger the event handler.
  // > jQuery(window).hashchange();
  // 
  // A more verbose usage that allows for event namespacing:
  // 
  // > // Bind an event handler.
  // > jQuery(window).bind( 'hashchange', function(e) {
  // >   var hash = location.hash;
  // >   ...
  // > });
  // > 
  // > // Manually trigger the event handler.
  // > jQuery(window).trigger( 'hashchange' );
  // 
  // Additional Notes:
  // 
  // * The polling loop and Iframe are not created until at least one handler
  //   is actually bound to the 'hashchange' event.
  // * If you need the bound handler(s) to execute immediately, in cases where
  //   a location.hash exists on page load, via bookmark or page refresh for
  //   example, use jQuery(window).hashchange() or the more verbose 
  //   jQuery(window).trigger( 'hashchange' ).
  // * The event can be bound before DOM ready, but since it won't be usable
  //   before then in IE6/7 (due to the necessary Iframe), recommended usage is
  //   to bind it inside a DOM ready handler.
  
  // Override existing $.event.special.hashchange methods (allowing this plugin
  // to be defined after jQuery BBQ in BBQ's source code).

  A number of property level validators are registered automatically, i.e added to each DataProperty.validators property
  based on {{#crossLink "DataProperty"}}{{/crossLink}} metadata.  For example,

  - DataProperty.dataType -> one of the 'dataType' validator methods such as Validator.int64, Validator.date, Validator.bool etc.
  - DataProperty.maxLength -> Validator.maxLength
  - DataProperty.isNullable -> Validator.required (if not nullable)

  @class Validator
  **/

  /**
  Validator constructor - This method is used to create create custom validations.  Several
  basic "Validator" construction methods are also provided as static methods to this class. These methods
  provide a simpler syntax for creating basic validations.

  Many of these stock validators are inspired by and implemented to conform to the validators defined at
  http://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.aspx

  Sometimes a custom validator will be required.
  @example
  Most validators will be 'property' level validators, like this.
  @example
      // v is this function is the value to be validated, in this case a "country" string.
      var valFn = function (v) {
          if (v == null) return true;
          return (core.stringStartsWith(v, "US"));
      };
      var countryValidator = new Validator("countryIsUS", valFn, {
          displayName: "Country", 
          messageTemplate: "'%displayName%' must start with 'US'" 
      });

      // Now plug it into Breeze.
      // Assume em1 is a preexisting EntityManager.
      var custType = metadataStore.getEntityType("Customer");
      var countryProp = custType.getProperty("Country");
      // Note that validator is added to a 'DataProperty' validators collection.
      prop.validators.push(countryValidator);
  Entity level validators are also possible
  @example
      function isValidZipCode(value) {
          var re = /^\d{5}([\-]\d{4})?$/;
          return (re.test(value));
      }

      // v in this case will be a Customer entity
      var valFn = function (v) {
          // This validator only validates US Zip Codes.
          if ( v.getProperty("Country") === "USA") {
              var postalCode = v.getProperty("PostalCode");
              return isValidZipCode(postalCode);
          }
          return true;
      };
      var zipCodeValidator = new Validator("zipCodeValidator", valFn,
          { messageTemplate: "For the US, this is not a valid PostalCode" });

      // Now plug it into Breeze.
      // Assume em1 is a preexisting EntityManager.
      var custType = em1.metadataStore.getEntityType("Customer");
      // Note that validator is added to an 'EntityType' validators collection.
      custType.validators.push(zipCodeValidator);
  What is commonly needed is a way of creating a parameterized function that will itself
  return a new Validator.  This requires the use of a 'context' object.
  @example
      // create a function that will take in a config object
      // and will return a validator
      var numericRangeValidator = function(context) {
          var valFn = function(v, ctx) {
              if (v == null) return true;
              if (typeof(v) !== "number") return false;
              if (ctx.min != null && v < ctx.min) return false;
              if (ctx.max != null && v > ctx.max) return false;
              return true;
          };
          // The last parameter below is the 'context' object that will be passed into the 'ctx' parameter above
          // when this validator executes. Several other properties, such as displayName will get added to this object as well.
          return new Validator("numericRange", valFn, {
              messageTemplate: "'%displayName%' must be a number between the values of %min% and %max%",
              min: context.min,
              max: context.max
          });
      };
      // Assume that freightProperty is a DataEntityProperty that describes numeric values.
      // register the validator
      freightProperty.validators.push(numericRangeValidator({ min: 100, max: 500 }));

  Breeze substitutes context values and functions for the tokens in the messageTemplate when preparing the runtime error message;
  'displayName' is a pre-defined context function that is always available.

  Please note that Breeze substitutes the empty string for falsey parameters. That usually works in your favor.
  Sometimes it doesn't as when the 'min' value is zero in which case the message text would have a hole
  where the 'min' value goes, saying: "... an integer between the values of and ...". That is not what you want.

  To avoid this effect, you may can bake certain of the context values into the 'messageTemplate' itself
  as shown in this revision to the pertinent part of the previous example:
  @example
      // ... as before
      // ... but bake the min/max values into the message template.
      var template = breeze.core.formatString(
          "'%displayName%' must be a number between the values of %1 and %2",
          context.min, context.max);
      return new Validator("numericRange", valFn, {
          messageTemplate: template,
          min: context.min,
          max: context.max
      });

  @method <ctor> Validator
  @param name {String} The name of this validator.
  @param validatorFn {Function} A function to perform validation.

  validatorFn(value, context)
  @param validatorFn.value {Object} Value to be validated
  @param validatorFn.context {Object} The same context object passed into the constructor with the following additional properties if not
  otherwise specified.
  @param validatorFn.context.value {Object} The value being validated.
  @param validatorFn.context.name {String} The name of the validator being executed.
  @param validatorFn.context.displayName {String} This will be either the value of the property's 'displayName' property or
  the value of its 'name' property or the string 'Value'
  @param validatorFn.context.messageTemplate {String} This will either be the value of Validator.messageTemplates[ {this validators name}] or null. Validator.messageTemplates
  is an object that is keyed by validator name and that can be added to in order to 'register' your own message for a given validator.
  The following property can also be specified for any validator to force a specific errorMessage string
  @param [validatorFn.context.message] {String} If this property is set it will be used instead of the 'messageTemplate' property when an
  error message is generated.

  @param [context] {Object} A free form object whose properties will made available during the validation and error message creation process.
  This object will be passed into the Validator's validation function whenever 'validate' is called. See above for a description

      var query = new EntityQuery("Customers")

  @example
      var query = new EntityQuery("Customers")
        .where("toLower(CompanyName)", "startsWith", "c");
  or to be even more baroque
  @example
      var query = new EntityQuery("Customers")
        .where("toUpper(substring(CompanyName, 1, 2))", FilterQueryOp.Equals, "OM");
  @method where
  @param predicate {Predicate|property|property path, operator, value} Can be either

    - a single {{#crossLink "Predicate"}}{{/crossLink}}

    - or the parameters to create a 'simple' Predicate

    - a property name, a property path with '.' as path seperators or a property expression {String}
    - an operator {FilterQueryOp|String} Either a  {{#crossLink "FilterQueryOp"}}{{/crossLink}} or it's string representation. Case is ignored
    when if a string is provided and any string that matches one of the FilterQueryOp aliases will be accepted.
    - a value {Object} - This will be treated as either a property expression or a literal depending on context.  In general,
    if the value can be interpreted as a property expression it will be, otherwise it will be treated as a literal.
    In most cases this works well, but you can also force the interpretation by making the value argument itself an object with a 'value' property and an 'isLiteral' property set to either true or false.
    Breeze also tries to infer the dataType of any literal based on context, if this fails you can force this inference by making the value argument an object with a 'value' property and a 'dataType'property set
    to one of the breeze.DataType enumeration instances.

  If the result of this selection "projection" contains entities, these entities will automatically be added to EntityManager's cache and will
  be made 'observable'.
  Any simple properties, i.e. strings, numbers or dates within a projection will not be cached are will NOT be made 'observable'.

  @example
  Simple data properties can be projected
  @example
      var query = new EntityQuery("Customers")
        .where("CompanyName", "startsWith", "C")
        .select("CompanyName");
  This will return an array of objects each with a single "CompanyName" property of type string.
  A similar query could return a navigation property instead
  @example
      var query = new EntityQuery("Customers")
        .where("CompanyName", "startsWith", "C")
        .select("Orders");
  where the result would be an array of objects each with a single "Orders" property that would itself be an array of "Order" entities.
  Composite projections are also possible:
  @example
      var query = new EntityQuery("Customers")
        .where("CompanyName", "startsWith", "C")
        .select("CompanyName, Orders");
  As well as projections involving nested property paths
  @example
      var query = EntityQuery("Orders")
        .where("Customer.CompanyName", "startsWith", "C")
        .select("Customer.CompanyName, Customer, OrderDate");
  @method select
  @param propertyPaths {String|Array of String} A comma-separated (',') string of property paths or an array of property paths.

  Exports selected entities, all entities of selected types, or an entire EntityManager cache.
  @example
  This method takes a snapshot of an EntityManager that can be stored offline or held in memory.
  Use the `EntityManager.importEntities` method to restore or merge the snapshot
  into another EntityManager at some later time.
  @example
      // let em1 be an EntityManager containing a number of existing entities.

  You can also control exactly which entities are exported.
  @example

      var bundle = em1.exportEntities(changes);

      em2.importEntities(bundle, { mergeStrategy: MergeStrategy.PreserveChanges} );
  Metadata are included in an export by default. You may want to exclude the metadata
  especially if you're exporting just a few entities for local storage.
  @example
      var bundle = em1.exportEntities(arrayOfSelectedEntities, {includeMetadata: false});
      window.localStorage.setItem("goodStuff", bundle);
  You may still express this option as a boolean value although this older syntax is deprecated.
  @example
      // Exclude the metadata (deprecated syntax)
      var bundle = em1.exportEntities(arrayOfSelectedEntities, false);
  You can export all entities of one or more specified EntityTypes.
  @example
      // Export all Customer and Employee entities (and also exclude metadata)
      var bundle = em1.exportEntities(['Customer', 'Employee'], {includeMetadata: false});
  All of the above examples return an export bundle as a string which is the default format.
  You can export the bundle as JSON if you prefer by setting the `asString` option to false.
  @example
      // Export all Customer and Employee entities as JSON and exclude the metadata
      var bundle = em1.exportEntities(['Customer', 'Employee'],
                                      {asString: false, includeMetadata: false});

  @return {String | Object} The export bundle either serialized (default) or as a JSON object.
  The bundle contains the metadata (unless excluded) and the entity data grouped by type.
  The entity data include property values, change-state, and temporary key mappings (if any).

  The export bundle is an undocumented, Breeze-internal representation of entity data

// 
// resize event - http://benalman.com/code/projects/jquery-resize/examples/resize/
// 
// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.6, Safari 3-4, Chrome, Opera 9.6-10.1.
// Unit Tests      - http://benalman.com/code/projects/jquery-resize/unit/
// 
// About: Release History
// 
// 1.1 - (3/14/2010) Fixed a minor bug that was causing the event to trigger

    // Because the window object has its own resize event, it doesn't need to be

    // browser. However, since certain browsers fire the resize event continuously
    // while others do not, enabling this will throttle the window resize event,
    // making event behavior consistent across all elements in all browsers.

    // window object resize event callbacks are bound.

    // provide this event for the window element, for other elements a polling
    // loop is initialized, running every <jQuery.resize.delay> milliseconds
    // to see if elements' dimensions have changed. You may bind with either
    // .resize( fn ) or .bind( "resize", fn ), and unbind with .unbind( "resize" ).
    // 
    // Usage:
    // 
    // > jQuery('selector').bind( 'resize', function(e) {
    // >   // element's width or height has changed!
    // >   ...

    // 
    // Additional Notes:
    // 
    // * The polling loop is not created until at least one callback is actually
    //   bound to the 'resize' event, and this single polling loop is shared
    //   across all elements.

    // 
    // While this plugin works in jQuery 1.3.2, if an element's event callbacks
    // are manually triggered via .trigger( 'resize' ) or .resize() those
    // callbacks may double-fire, due to limitations in the jQuery 1.3.2 special
