Strictly speaking, it is probably not accurate to talk of two dimensional
models in mtm2. But, for the sake of learning BinEdit, let's assume
a 2D model is anything that has only one side visible. Naturally,
then, a simple 2D model must be either a triangular or four-cornered bin.
Examples of 2D models would be all the trees in mtm2, the cover to the
secret passage in Chase the Dragon by Guitar Bill, and the "wrong way"
signs in Dark Star by Oliver Pieper and in CNR 008 by GyverX. There
are more, but that should give you the idea. The point here is that
these models, like a sheet of paper, all have a width and a height but
no thickness/depth of any significance.
To make a bin we need to do three things
1. define some verticies
