Finished importing JTransforms FFT library

Finished importing the JTransforms FFT Library into the
main project. The microphone class has also been subjugated
to a minor cosmetic series of changes hopefully resulting
in a better object-oriented design. An android project
has also been created. The project was tested on an
Android device to see whether everything ran, and,
surprisingly, everything did.

Basic ui
Audio playback implemented

Audio output has been implemented. There is a
fairly large latency on my test platform, and
this change isn't doing any sort of audio
processing. Some work should be done to reduce
the latency at a later point.
