### `edge_profile()`
Using the `edge_profile()` module, you can provide a 2D profile shape and it will be linearly
extruded to a mask of the apropriate length for each given edge. The resultant mask will be
tagged with "mask" so that you can difference it away with `diff("mask")`. The 2D profile is
tagged with "remove" so that you can difference it away with `diff()`
with the default "remove" tag. The 2D profile is
assumed to be oriented with the BACK, RIGHT (X+,Y+) quadrant as the "cutter edge" that gets
re-oriented towards the edges of the parent shape. A typical mask profile for chamfering an
edge may look like:
