Desired levels/levelsplot feature

[melaniedrake]

I would love to be able to use Sys.CrystalSymmetry and Sys.CrystalOrientation as the Orientation inputs to levels and levelsplot functions. That way it would be simple to get the spectrum and corresponding energy levels in the same file without having to calculate different angles to describe the orientation for the levelsplot and pepper functions.

Thanks for the suggestions, that would make a lot of sense. We'll add it to our to-do list.
