* @name MarkerManager
* @version 1.1
* @copyright (c) 2007 Google Inc.
* @author Doug Ricket, others
*
* @fileoverview Marker manager is an interface between the map and the user,
* designed to manage adding and removing many points when the viewport changes.
*
* How it Works:
* The MarkerManager places its markers onto a grid, similar to the map tiles.
* When the user moves the viewport, it computes which grid cells have
* entered or left the viewport, and shows or hides all the markers in those
* cells.
* (If the users scrolls the viewport beyond the markers that are loaded,
* no markers will be visible until the EVENT_moveend
* triggers an update.)
* In practical consequences, this allows 10,000 markers to be distributed over
* a large area, and as long as only 100-200 are visible in any given viewport,
* the user will see good performance corresponding to the 100 visible markers,
* rather than poor performance corresponding to the total 10,000 markers.
* Note that some code is optimized for speed over space,
* with the goal of accommodating thousands of markers.
