﻿// Clusterer.js - marker clustering routines for Google Maps apps
//
// Using these routines is very easy.
//
// 1) Load the routines into your code:
//
//        <script src="http://www.acme.com/javascript/Clusterer.js" type="text/javascript"></script>
//
// 2) Create a Clusterer object, passing it your map object:
//
//        var clusterer = new Clusterer( map );
//
// 3) Wherever you now do map.addOverlay( marker ), instead call
//    clusterer.AddMarker( marker, title ).  The title is just a
//    short descriptive string to use in the cluster info-boxes.
//
// 4) If you are doing any map.removeOverlay( marker ) calls, change those
//    to clusterer.RemoveMarker( marker ).
//
// That's it!  Everything else happens automatically.
//
