Experimental Releases

In order to be able to get stuff up quicker without destabilizing things, I'm trying something a little different. I've added a "trove experimental" package in addition to the existing "trove" package. "Experimental" releases are just that: you should consider the API subject to change. I pretty much never release without unit tests passing, but that might the extent of testing some will get.

To celebrate the new package, 2.1a2 has been released in the experimental package. There is one bug fix, but it's mostly features.
