touchesEnded
we must not do what we did in the other two touch methods;
here we will only update the
tankDestination
and

if (self.gameState == kGameStatePlaying)
{
if([touches count] == [[event

method is called to update the
final position and rotation. After updating these attributes for the local tank a net-
