CLI for reading MCNP meshtal files to h5m.

The meshtallies may have different mesh bounds, so they can't be tags on the same mesh. They could in principle be different meshsets in the same h5m, but this is a bad idea because it greatly complicates the process of actually using the h5m (both in PyNE and for visualization).

Nope.
