Test Paramak compatibility with Shift

[jbae11]

After #234 , @jbae11 should test if Paramak-generate h5m files can be directly used with Shift, and that the results match that of OpenMC, for a simple problem.

Might also want to wait for me to finish #236 sorry for slowing this down

haha nooo take your time you're moving incredibly quickly I'm trying to catch up

The develop branch of the paramak now has an improved export_dagmc_h5m method that can add a graveyard and custom tags.

Here is an example of how to use the paramak develop branch to make a shift dagmc file.

Let me know if this works at your end @jbae11

I've updated the paramak (PR #240) so that the material tags work a little better with DAGMC (no more accidental vacuum materials).

I've also run the example here and am getting fluxes in all cells.

The mesh resolution will need to be increased to get the flux numbers closer to the CSG values
