AEP: 13_abund_rel_vec.R

• This may do nothing (and I could not check – at the time I did this).
• Please add a @return
• Does “zsl <- traj.sublist.zero[[depl]]$trajectories” actually work?

Added return, added better description, example, and cleaned up with commit a9381e5. A lot of these functions are awkward because the trajectories (projections) are stored in a list of lists. It's not the best; I'm trying to brainstorm a better way to deal with them.
