grafx - Extensible Java Graphics Package Code

Making WellStorage final. Defining copyInto() and makeEmptyWell() here.

Making MutableLayer final class.

Finished combineWellWithBlock().

Implemented blockFits().

Making progress on BlockPlacementStrategy.

Starting work on evalWithNextBlock().

Making computeAllUniqueOrientations() public, because it or something like it
is needed by the artificial intelligence code.

Adding BlockPlacementStrategy.

Adding another comment to EvalFunction.

Removing entire package net.blockout.production.ai. It was in a state where
there were only some basic interfaces; they were never implemented. I think
I'm going to start the a.i. code from ground up, removing this to avoid
confusion.
