Removed two old useless wrong stupid functions that have been left into wrap/trimesh.h for unforgivable lazyness...

Crease Angle
Assume che:
la mesh abbia la topologia ff
la mesh non abbia complex (o se li aveva fossero stati detached)
Abbia le normali per faccia normalizzate!!
Prende una mesh e duplica tutti gli edge le cui normali nelle facce incidenti formano un angolo maggiore
di <angle> (espresso in rad).
foreach face
foreach unvisited vert vi
scan the star of triangles around vi duplicating vi each time we encounter a crease angle.
the new (and old) vertexes are put in a std::vector that is swapped with the original one at the end.
