// REMOVE_DUPLICATE_VERTICES Remove duplicate vertices upto a uniqueness
// tolerance (epsilon)
//
// Inputs:
// V #V by dim list of vertex positions
// epsilon uniqueness tolerance (significant digit), can probably think of
// this as a tolerance on L1 distance
// Outputs:
// SV #SV by dim new list of vertex positions
// SVI #V by 1 list of indices so SV = V(SVI,:)
// SVJ #SV by 1 list of indices so V = SV(SVJ,:)
//
// Example:
// % Mesh in (V,F)
// [SV,SVI,SVJ] = remove_duplicate_vertices(V,1e-7);
// % remap faces
// SF = SVJ(F);
//
