-----------------------------------------------------------+----------------
There is a correspondance between groups of Dirichlet characters and
Galois groups of abelian fields (over Q). We implement here three
functions
* the conductor of an abelian field
* the set of Dirichlet characters of an abelian field
* the fixed field of a Dirichlet character
