New description:
This patch implements reflection groups to work with finite
(crystallographic, real, complex) reflection groups. It is based on the
GAP3 package **chevie**.
{{{
sage: W = ReflectionGroup(['A',2],5,23); W
Reducible complex reflection group of rank 7 and type A2 x ST5 x H3
sage: W.irreducible_components()
[Irreducible real reflection group of rank 2 and type A2,
Irreducible complex reflection group of rank 2 and type ST5,
Irreducible real reflection group of rank 3 and type H3]
}}}
