particle tracking

[ckhuang-lanl]

Hello,

I have implemented particle tracking in my input deck. To do this in a way consistent with current VPIC, I am using the particle weight for the storage of particle tag. But to make sure that these test particles do not generate currents, they needed to be defined in a separate species list and managed in input deck for particle push (using a dummy field array) and boundary handling, which works but is cumbersome.

I wonder in the future version, will VPIC support some better way to track particles, e.g., allow the user to skip current deposition in the pusher for some species, or define separate variable for tagging the particles.

Thanks!
