Issue with placing input ASTs for a case with complex region shape

Just brainstorming about this issue a little bit. I don't think the issue is that the convex hull isn't working properly, it's more the case that what you really need is a concave hull, which would allow for inside angles greater than 180 deg).

I managed to find a python code snippet online that uses Delaunay triangulation to create a convex hull around a set of datapoints. Using this method would require manually setting an "alpha" value for how pliable the edges should be, meaning that there should probably be some sort of visual diagnostic to check that the appropriate "alpha" value is being set.

#789 should fix this issue.
