Name change

[tyarkoni]

This package needs a new name that doesn't imply any commitment to either (a) psychological data or (b) PyMC. Down the road, we may want to add other back-ends (e.g., Stan), so we should be maximally agnostic.

[jake-westfall]

Only other name I've thought of so far is bambi: bayesian model building interface

[tyarkoni]

Done!
