maxLat	Maximum latitude of bounding box.
maxLon	Maximum longitude of bounding box.
cells	Initialized by this.
maxNumberOfCells	Value of 0 indicates return as many as you can. Any positive number will only return that number of cells.

I have tried the readwrite lock interfaces but have found it unstable.

I am using the standard Mutex and it seems to be much more stable across all platforms. More testing needs to occur for the ReadWriteMutex. For now we will use Mutex.
