Symmetry group base classes.

Design (see plan): group theory by explicit component transformation with generator matrices — no abstract index gymnastics. A gauge group knows the generator matrices of each representation label; a discrete group knows the finite generator matrices of each irrep and which field multiplets it acts on.

Classes

GaugeGroup(name[, coupling])	Continuous (gauged) symmetry group.
SymmetryGroup(name)	Base class for all symmetry groups.
