running list of arepo front end issues

[dnarayanan]

• [x] What is the difference between gas and PartType0 fields? Is one for the particle and other for the mesh?

• [x] What do the fields look like for an idealized Arepo simulation?

• [x] Do we want to allow yt3.x runs where we can read in the simulation as though its a particle-based simulation, but pass through the arepo front end?

• [x] What do we do about non-illustris type galaxy formation models that don't have the GFM_ tags?

• [ ] Right now the automatic dust masses are turned off. If we can get a copy of a McKinnon snapshot, we can see what the fields look like, and use those instead.

• [ ] black holes are currently commented out of arepo2pd...need to get a snapshot that has BHs to test them.

• [x] We've currently commented out the dust grid generation stuff in arepo_vornoi_grid_generate. will update as i have an idea how to include this

(note, this ^ will require refactoring dust_grid_gen some, so for now we'll put a place holder in arepo_tributary)
