Research direction

Start by inspecting the declarations in signpost_intrinisc_triangulation.h and searching the repository for definitions of equivalentPointOnIntrinsic and equivalentPointOnInput. Reproduce the unresolved external linker errors with a use of SignpostIntrinsicTriangulation. Done means the functions are defined and the affected code links successfully.

Description

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?
