Basic Function Computing the intersection between a trimesh and a plane. It returns an EdgeMesh without needing anything else.
Note: This version always returns a segment for each triangle of the mesh which intersects with the plane. In other
words there are 2*n vertices where n is the number of segments fo the mesh. You can run vcg::edge:Unify to unify
the vertices closer that a given value epsilon. Note that, due to subtraction error during triangle plane intersection,
it is not safe to put epsilon to 0.
