Comment (by wishcow):
It seems that the code for __forward_image is implemented for any morphism
P^n^ -> P^m ^(or n-1, m-1 to be precise with the code), yet the examples
are all for endomorphisms of projective space. I think it would be better
to either add examples with different domain and codomain, or add an
assertion that checks n=m and states otherwise that only endomorphisms are
currently implemented.__
