Decide on tool deprecation

[Jason Vander Heiden]

We should get some input from users on whether we should remove GapRecords (because of the improvements to MakeDb-igblast) and AnalyzeAa (in favor of putting it in alakazam) for v0.3.0. My inclination would be yes, but I'm not sure how everyone else feels.

Either, we should rename GapRecords to AlignRecords, as it will no longer include the gapping functionality.

Looks like the decision is to remove them. I removed both AnalayzeAa and GapRecords from setup.py, and renamed GapRecords to AlignRecords. I'm inclined to keep them in the repo, just in case they need to be revived, but exclude them from the installation process.
