Comment:
Need to fix the merge issue.
From looking through the commits I see a couple things to fix:
in nth_iterate:
these checks are done in __call__ with better coercion, so not needed
here.
if self.codomain()!=f.domain():
raise TypeError("Point is not defined over domain of
function")
use .is_endomorphism() instead:
if f.domain() != f.codomain():
raise TypeError("Domain and Codomain of function not equal")
in nth_iterate_map
use is_endomorphism() check
