Comment (by cremona):
Thanks a lot for your help and suggestions. I did not need that ideal
comparison for this ticket anyway, so I have left alone the ideal
comparison function except to tidy the code as you suggested. the two
elliptic curve comparison functions have gone, replaced by little key
comparison functions in the code where they are used -- much better and
shorter and faster!
I am doing some final testing and then will upload a new branch in which
you will find no utility functions in the wrong place.
In the other tickets where you are dealing with comparing pari objects,
good luck: if you have not already discovered this, you will find that
hunderds of number field factorizations have their orders changed....
