[ENH] - extra bval parsing for number of shells

[edickie]

In response to issue #64 and discussion during the hack here is a little addition to the vectors utility that can determine and report on the number of the shells (as well as masks for each shell).

Currently, it is outside of DiffusionTable because I'm unsure if we want all the methods integrated..

I believe this from #29 is highly related to this PR.

EDIT: I'll go through this PR tomorrow. Thanks for updating Erin!
