improved - added lots of explaining labels as well as a total
probability-meter.
init - added WavePacket, used heavily in the click and drag feature as
well as the testing (this cleverly uses inheritance).

inheritance.

well as draggable through the MouseAdapter class.
refactor - moved all the wave packet calculations out of State into
WavePacket.
improved - fixed minor thing in Complex (changed return values Boolean
