clearoverlays in google maps v3 api

Since api v2 has been now officially deprecated, I've been recently relearning some of the stuff to the new v3 api and trying to figure out the differences. One of the annoying things (as of writing) is the lack of clearOverlays().

There's a few ways to do it but the easiest way to do is maintain a separate array of markers then remove them one by one. So the code would look like :

while(markerArrayList[0]){
   markerArrayList.pop().setMap(null);
}

We keep going through the array in the while loop and pop an item until we don't have any more at which point the markerArrayList[0] will return false and stop the loop.

Example code here

I hope this helps some out there! Please feel free to comment!
