Note, this creates a homomorphism from WeightModel to (l_type with all attributes mapped to nothing).

It's going to say there's a lot of changes because I merged #93 into it

[neonWhiteout]

Thing is, this is literally just half of a @stratify call. Need to figure out what I can pull out from both and use.

PLEASE NOTE THIS HAS #93 MERGED INTO IT!!! This will cause a lot of reformatting to occur throughout the project, to shorten lines and get tabs to be 2 spaces rather than 4.
