 * purpose: a structured legend that supports grouped layers, visibility, 
 *          expand/collapse, and queryability
 *
 * author: Paul Spencer (pspencer@dmsolutions.ca)
 *
 * The original kaLegend code was written by DM Solutions Group.  Lorenzo
 * Becchi and Andrea Cappugi contributed a bunch of code too!
 *
 * TODO:
 * 
 *   - drag and drop layer re-ordering would be nice, see script.alicio.us

 *
 * To use kaLegend:
 * 
 * 1) add a script tag to your page:
 * 
 * <script type="text/javascript" src="kaLegend.js"></script>
 *
 * 2) add a <div> element to your page to contain the legend.  The div must
 *    have a unique id:
 *
 * <div id="legend"></div>
 * 
 * 3) create a new instance of kaLegend and pass it the id of the div:
 * 
 * myKaLegend = new kaLegend( 'legend' );
 *
 * and that's it :)
 *
