//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

// Note that for maximum portability, libraries that are not jQuery should
// declare themselves as anonymous modules, and avoid setting a global if an

EXTENDED FUNCTIONALITY FOR NAVIGATION DROPDOWN MENUS

1. For desktop navigation - Handles opening dropdown menus on hover with a little delay
to prevent accidental opening of neighbour menus if user just briefly passes over another items.

2. For mobile navigation - add fancy slide animation when expanding collapsible dropdown menus

See jquery ready function at the bottom of this script, where we initialize this funcionality.

//
// Jquery Window Busy ('Please wait') Popup Message
// Version: 1.0.2 (14.1.2013)
//
// Shows 'Please wait' window busy popup when page is submitted, or ASP.NET ajax (UpdatePanel or other ajax requests) or JQuery ajax request are invoked.
//
// Usage:
// <script type="text/javascript">
//   $(function () {
//     $.windowbusy();
//     // or you can set parameters: $.windowbusy({ delay: 3000, text: 'Please wait ...' });
//   });
// </script>
//
// Optional parameters:
//  delay: miliseconds before window busy dialog is shown (default 3 seconds)
//  text: text message to be displayed in the popup (default "Please wait ...")
//  popupHtmlTemplate: custom html code for the popup to render. In the code put {message} in a place where to output text message.
//      default popupHtmlTemplate: <span class="WindowBusyPopup" style="position: absolute; z-index: 9999; top: 40%; left: 40%; border: 1px solid #444444; background-color: #ffffff; padding: 10px 40px; text-align: center">{message}</span>
//  enabledForAjaxCalls: if indicator is enabled for ajax calls
//  enabledForPageLoad: if indicator is enabled for page calls
//
//  METHODS:
//  $.windowbusy.disableForAjaxCalls(); // Disables indicator on ajax calls
//  $.windowbusy.disableForPageLoad(); // Disables indicator on page load
//
// IMPORTANT NOTES:
// Links and buttons that cause download of files (zip, pdf, xml, ...) should prevent showing window busy dialog, by calling $.windowbusy.prevent() function in onclick event.
// This is required because otherwise, downloading files would show window busy dialog forever in Chrome or Firefox (if browser settings are set to save downloaded files automatically on disk without showing any download dialogs). 
// Examples of link or button that trigger file download:
//   <a href="download.zip" onclick="$.windowbusy.prevent()">Download</a>
//   <input type="button" onclick="$.windowbusy.prevent(); YourFunction();" value="Download"</a>
