Triangulate Mesh (Heavy)

This node tesselates all polygons that are not triangles, using this code:

# for all objects/bm incoming:
#
for f in bm.faces:
    coords = [v.co for v in f.verts]
    indices = [v.index for v in f.verts]

    if len(coords) > 3:
        for pol in tessellate([coords]):
            new_faces.append([indices[i] for i in pol])
    else:
        new_faces.append([v.index for v in f.verts])

which may not be super efficient.

This node is a heavier implementation of Triangulate until someone finds time to figure out the bug in the original node.
