Memory Leak in MarkerClustererPlus When Removing and Adding Clusters Repeatedly

[GoogleCodeExporter]

Demo link or sample code:
http://relaysupply.com/markerclustererplus/examples/simple_example_mem_leak.html
What steps will reproduce the problem?
1. Just view the page.  There are about 20 clusters.  Each cluster gets 
setMap(null) called on them, and then setMap(map) every 2 seconds using 
setTimeout.
2. The bounds_changed event listener is attached to the map rather than the div 
of the cluster.  As a result, it is never cleared by the onRemove function.

Expected result:
Memory should not leak within 5 minutes.

Actual result:
20 mb's leaked in 2 minutes.

Version: Trunk

Browser / Operating System:
Chrome 28 / Windows 7

Additional comments:
Attached screen shots of heap dumps in chrome dev tools with a timer to show 
how fast the memory leak can accumulate within 2 minutes of 20 clusters being 
swapped every 2 seconds.

Fixed by adding a reference to the bounds_changed event listener so that it can 
be removed in the onRemove function.  Demo here:
