//This document hold all of the required functions for the Event Ticker and the Google Maps API.
//Note that all these were written for EXODUS -- the core files needed to run the Google Maps API are
//hosted directly on Google's site and referenced to at the top of index.html.


//Google Maps Functions-------------------------------------------------------------------
//Basically for use in setting up the points on the map-----------------------------------

  // A function to create the marker for the Google Maps API
  function createMarker(point,name,html) {
	var marker = new GMarker(point);
	GEvent.addListener(marker, "click", function() {
	  marker.openInfoWindowHtml(html);
	});
	gmarkers.push(marker);
	return marker;
  }
  
// This function picks up the click and opens the corresponding info window. Easier than using GEvent every time, also works better with the list randomizer. go figure.
      function myclick(i) {
        GEvent.trigger(gmarkers[i], "click");
      }
