Specify Important Edges

[JarredAllen]

For ROIs, we need some way to specify which edges are relevant and could have ants crossing them.

The current plan is to go into roimodify.py and add a tool for selecting the important edges for each ROI. Then, in the edgefromtrack.py script, we need to modify the file to only allow ants to enter and exit from one such edge, if there's one.

Specifying the important edges has been handled as of ea3a27d, but no automatic detection is in place.

The code still doesn't do anything with the values, either.

Not quite sure what you meant by automatic detection, but I realized you could by default assume that in a rectangle the short edges are the important ones, and in any other shape assume all edges are important? This would probably get it right most of the time.

@mdonaldsonmatasci That's what I meant by automatic detection.

ok sounds good

As of 9b4827f, the code now uses the important edges and classifies tracks as going from one important edge to another important edge only, if a user specifies them. Because specifying the important edges is easy to do, I'm going to call enabling the code to automatically guess at which edges are important to be a low-priority concern.

It may be easy, but if we have to do it manually 70 * 8 * 3 times (for each video) it's pretty laborious. Would it be possible to specify them once for a whole set of videos, like all of Pi 8 from experiment 1? That would be only 24 times which seems more doable.

@mdonaldsonmatasci I'll look into reusing manually specified ROIs in a bit, but my gut feeling is that it should be possible.
