Comment:
I just uploaded a patch that allows you to construct relative number field
morphisms as above (the code simply wasn't written accept something like
that). I just made it go recursively through the list you provide, so in a
tower of fields, you only need to provide the images up to the point where
your morphism is the identity.
I'll set this to needs review after I do a full doctest overnight (the
number_field module passes all doctests).
