Formatted code to my liking.
Removed the classes CircularArrayQueue, Queue, QueueEmptyException, and
QueueFullException and the package mbkp.pi.exceptions. No use for them
any more.
Labeled code to make it more readable.
Relocated GZipFile class to PiMeth.
Added call to gZipIt() to writePi().
For once im acutally using (relatively) good code hygine.
