Checkpoint differentials.
Checkopint differentials.
Update dependencies in README.
Differentials works on example f11.

Differentials now work on an example. (From Deconinck,Patterson.)
One part that needs improvement is the modular reduction of
b*P by f. Certain combinations of generators and ring extensions
work better than others.
Add comments on functional holomophic differentials.

Approximately half of the differentials examples produce
correct output. Comments are made on which ones work
and which ones don't.
Differentials works on all examples.

differentials:differentials() now works. Performance is
still relatively poor. Next steps include improving
integral basis and singularities performance, since
differentials highly depends on these, as well as
determining optimal domains for the modular reduction
step in differentials:mnuk_conditions().
