Comment:
Note that when I implemented this I noticed that the original
implementation for ideals was inconsistently ordering the coordinates. In
particular it labelled `a^2x2 + ax1 + ax0` and then created the
coordinates (x2,x1,x0) in the ring k[x0,x1,x2]. This caused issues for
morphisms, so I made this consistent: i.e. coordinates (x0,x1,x2). I also
allowed for weil restrictions of relative number fields (to the base
field) instead of just absolute number fields. These are the only two
changes to the original implementation.
