public class TouchEventPool
TouchEventPool provides a RingBuffer of jME TouchEvents to help with garbage
collection on iOS. Each TouchEvent is stored in the RingBuffer and is
reused if the TouchEvent has been consumed.
If a TouchEvent has not been consumed, it is placed back into the pool at the
end for later use. If a TouchEvent has been consumed, it is reused to avoid
creating lots of little objects.
If the pool is full of unconsumed events, then a new event is created and provided.
