New description:
The aim of this ticket is changed to merge Julian's function field
personal codes into function field package which includes the initial
purpose of the ticket:
- Implement a method `absolute_field()` for function fields, i.e.,
collapse a tower of separable extensions to one simple extension.
and
- primitive_element: compute a primitive element of the function field
over base.
- change_generators: changing the base rational function field over which
the function field is defined.
- inversion for function field homomorphisms
