/*==================================================
* 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 from the MIT copy of Timeline:
* Include this file in your HTML file as follows:
*
* <script src="http://static.simile.mit.edu/timeline/api-2.3.0/timeline-api.js"
* type="text/javascript"></script>
*
*
* To host the Timeline files on your own server:
* 1) Install the Timeline and Simile-Ajax files onto your webserver using
* timeline_libraries.zip or timeline_source.zip
*
* 2) Set global js variables used to send parameters to this script:
* Timeline_ajax_url -- url for simile-ajax-api.js
* Timeline_urlPrefix -- url for the *directory* that contains timeline-api.js
* Include trailing slash
* Timeline_parameters='bundle=true'; // you must set bundle to true if you are using
* // timeline_libraries.zip since only the
* // bundled libraries are included
*
* eg your html page would include
*
* <script>
* Timeline_ajax_url="http://YOUR_SERVER/javascripts/timeline/timeline_ajax/simile-ajax-api.js";
* Timeline_urlPrefix='http://YOUR_SERVER/javascripts/timeline/timeline_js/';
* Timeline_parameters='bundle=true';
* </script>
* <script src="http://YOUR_SERVER/javascripts/timeline/timeline_js/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.
