SignpostIntrinsicTriangulation perhaps missing some function definitions?

[mgsutton]

It seems like the functions equivalentPointOnIntrinsic(const SurfacePoint& pointOnInput) and equivalentPointOnInput(const SurfacePoint& pointOnIntrinsic) may be declared but not defined for SignpostIntrinsicTriangulation? When I grep the master branch I seem to find their declarations in signpost_intrinisc_triangulation.h, but I can't seem to locate a definition. Obviously, my first clue was unresolved external link errors when I trie to use them. Just curious if their implementation might have existed at one time?

Ah, you're totally right! They must have gotten dropped or something. I certainly created implemented these functions for our paper, but perhaps they never made their way in to the code release in this repo. I just created an issue here #85
