grafx - Extensible Java Graphics Package Code

Partial changes. Certainly won't compile. Working on the block orientations -
there are sets of orientations that are identical in shape, only that their
centers of rotations differ.

In BlockGenerator, redoing rotateX(), rotateY(), and rotateZ() to accept and
return a Block instead of a Layer[]; this is so that the center of rotation can
be rotated too.

Modifying comments.

Making progress on the Move comments.

Breaking the compile, but I took a long time in figuring out a good way to
represent the "post drop" movements with bits.

Adding a long comment with exploratory dissertation on how bits can represent
concepts.

Decrease epsilon to 0.001.

Decreasing qSearchBreadth to 32, increasing level 22 clear layers to 13.

Specifying the new required 'epsilon' field in ComputerPlayer constructor.

Doing some work on choosing a random move that is the best within epsilon.
