More in TODO.txt, creating case studies.

Adding covered-hole-magic.blo.

Adding amazing.blo.

Adding more to TODO.txt and adding excellent.blo because it was a really
excellent game.

Re-adding TODO.txt. Many plans. The Universe is expanding.

Temporarily adding fixed-covered-hole-metric.mp4.

Removing excellent-7er-blocks.blo and mega-excellent-6er-blocks.blo.

Changing fixed-covered-hole-metric.blo.

Remove TODO.txt. It's pretty much done.

In LocalBlockoutBoard.java, adding nice little feature of rendering covered
holes (using phantom block technology) after clearing layers; the rendering of
covered holes stays for about half a second and then fades away in about half a
second.
