Includes PR 32: fixes `TH2.edges` and adds `TH2.allnumpy`.
0.3.2
Fixed 24, 27, 28, and 30.
0.3.1
Cleaning up the histogram interface to be more mature.
0.3.0
Minimum version for awkward is now 0.7.0.
Histograms now return Numpy arrays instead of lists of numbers for `values`, `allvalues`, `variances`, `allvariances`.
Added `edges`, `alledges`, `bins`, and `allbins`.
0.2.11
pt`, `eta`, `phi`, and `mass` caching on `TLorentzVector.ArrayMethods` now happens only at the deepest level of `JaggedArray` nesting. That means that short-lived views (projecting through a jagged table, for instance) won't invalidate that cache.
