Improve JetShape projection's interface

The JetShape? projection requires all sorts of crap involving internally binning the distributions and holding an un-reseatable reference to an external collection of jet axis vectors. This means that internal and external vector indices have to match up. Yuck!
It's not clear that this projection can be easily cached in general, but the interface can certainly be improved.
