Add conjugacy classes in Weyl groups

[fingolfin]

Of course we can compute conjugacy classes by first converting to a permutation group, computing it there, and converting back (and this might very well be a first implementation).

But in practice one ideally wants specific representatives (not random ones), and perhaps even a certain order of conjugacy classes, and "parametrized"

As to what is desired one might want to ask @frankluebeck
