Threshold length for curve shortening with EdgeFlipGeodesicSolver

[areiner222]

Thanks for this great work! I'm not an expert in 3D geometry and searched for a while until I found your geodesic path implementation. Exactly what I need!

I want to use the EdgeFlipGeodesicSolver to straighten jagged loops for mesh segmentation, but some of my loops can be reduced to a point so I think I need to set the threshold length as described in your paper. Is there any way this can be exposed with the python api?
