moveTo methods not removing tiles from cache correctly about route-me HOT 2 CLOSED

I've added a call to MapViewViewController.m on line 88 (currently commented 
out) to debug issue 18 - build 
and launch first with this code commented out and observe the marker position, 
then uncomment the call to 
moveToLatLong. When you launch again, you'll see that the marker is initially 
shown in the wrong place because 
the underlying map tiles are not in sync. Zooming in or out to another zoom 
level will show the marker in the 
correct position, but the old tiles have not been removed properly for the 
original zoom level. 

Fixed by Joe - thanks Joe!
