/*==================================================
* 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://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 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:
* var Timeline_ajax_url -- url for simile-ajax-api.js
* var Timeline_urlPrefix -- url for the *directory* that contains timeline-api.js
* Include trailing slash
* var 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>
* var Timeline_ajax_url="http://YOUR_SERVER/javascripts/timeline/timeline_ajax/simile-ajax-api.js";
* var Timeline_urlPrefix='http://YOUR_SERVER/javascripts/timeline/timeline_js/';
* var 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.
*
* 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

/*==================================================
*
* To enable a single event listener to monitor everything
* on a Timeline, we need a way to map from an event's icon,
* label or tape element to the associated timeline, band and
* specific event.
*
* Thus a set format is used for the id's of the
* events' elements on the Timeline--
*
* element id format for labels, icons, tapes:
* labels: label-tl-<timelineID>-<band_index>-<evt.id>
* icons: icon-tl-<timelineID>-<band_index>-<evt.id>
* tapes: tape1-tl-<timelineID>-<band_index>-<evt.id>
* tape2-tl-<timelineID>-<band_index>-<evt.id>
* // some events have more than one tape
* highlight: highlight1-tl-<timelineID>-<band_index>-<evt.id>
* highlight2-tl-<timelineID>-<band_index>-<evt.id>
* // some events have more than one highlight div (future)
* You can then retrieve the band/timeline objects and event object
* by using Timeline.EventUtils.decodeEventElID
*
*==================================================
*/
/*
* eventPaintListener functions receive calls about painting.
* function(band, op, evt, els)
* context: 'this' will be an OriginalEventPainter object.
* It has properties and methods for obtaining
* the relevant band, timeline, etc
* band = the band being painted
* op = 'paintStarting' // the painter is about to remove
* all previously painted events, if any. It will
* then start painting all of the visible events that
* pass the filter.
* evt = null, els = null
* op = 'paintEnded' // the painter has finished painting
* all of the visible events that passed the filter
* evt = null, els = null
* op = 'paintedEvent' // the painter just finished painting an event
* evt = event just painted
* els = array of painted elements' divs. Depending on the event,
* the array could be just a tape or icon (if no label).
* Or could include label, multiple tape divs (imprecise event),
* highlight divs. The array is not ordered. The meaning of
* each el is available by decoding the el's id
* Note that there may be no paintedEvent calls if no events were visible
* or passed the filter.
