This looks good to me! I left a few nits. I'll merge tomorrow -- if you don't get around to fixing the nits by then, I'll just do it myself as I merge I think.

It'd be nice to expand this comment to explain that the first N indices are the free regions -- or at least comment on that somewhere.

This isn't addressing the question of auxillary methods for
BitMatrix. I'm also not immediately sure what kind of testing is appropriate.
