/*==================================================
*
* Timeline API
* ------------
*
* This file will load all the Javascript files
* necessary to make the standard timeline work.
* It also detects the default locale.
*
* To run Timeline directly from the www.simile-widgets.org server
* include this fragment in your HTML file as follows:
*
* <script src="http://api.simile-widgets.org/timeline/2.3.1/timeline-api.js"
* type="text/javascript"></script>
*
*
* To host the Timeline files on your own server:
*
* 1) Install the Timeline files onto your webserver using
* the minimal distribution "timeline_<version>_minimal.(zip|tar.gz)" found at
*
* http://code.google.com/p/simile-widgets/downloads/list
*
* 2) Set the following global js variable used to send parameters to this script:
* var Timeline_ajax_url -- URL for simile-ajax-api.js
* var Timeline_urlPrefix -- URL for the *directory* that contains timeline-api.js
* on your web site (including the trailing slash!)
*
* eg your HTML page would include
*
* <script>
* var Timeline_ajax_url="http://YOUR_SERVER/apis/timeline/ajax/simile-ajax-api.js";
* var Timeline_urlPrefix='http://YOUR_SERVER/apis/timeline/';
* </script>
* <script src="http://YOUR_SERVER/javascripts/timeline/timeline-api.js"
* type="text/javascript">
* </script>
*
* SCRIPT PARAMETERS
*
* This script auto-magically figures out locale and has defaults for other parameters
* To set parameters explicity, set js global variable Timeline_parameters or include as
* parameters on the url using GET style. Eg the two next lines pass the same parameters:
* Timeline_parameters='bundle=true'; // pass parameter via js variable
* <script src="http://....timeline-api.js?bundle=true" // pass parameter via url
*
* Parameters
* timeline-use-local-resources --
* bundle -- true: use the single js bundle file; false: load individual files (for debugging)
* locales --
* defaultLocale --
* forceLocale -- force locale to be a particular value--used for debugging. Normally locale is determined
* by browser's and server's locale settings.
*
* DEBUGGING
*
* If you have a problem with Timeline, the first step is to use the unbundled Javascript files. To do so:
* To use the unbundled Timeline and Ajax libraries
* Change
* <script src="http://api.simile-widgets.org/timeline/2.3.1/api/timeline-api.js?bundle=true" type="text/javascript"></script>
* To
* <script>var Timeline_ajax_url = "http://api.simile-widgets.org/ajax/2.2.1/simile-ajax-api.js?bundle=false"</script>
* <script src="http://api.simile-widgets.org/timeline/2.3.1/api/timeline-api.js?bundle=false" type="text/javascript"></script>
*
* Note that the Ajax version is usually NOT the same as the Timeline version.
* See variable simile_ajax_ver below for the current version
*
