The category of group algebras over base_ring.
EXAMPLES:
sage: C = GroupAlgebras(QQ); C
Category of group algebras over Rational Field
sage: sorted(C.super_categories(), key=str)
[Category of hopf algebras with basis over Rational Field,
Category of monoid algebras over Rational Field]
This is just an alias for:
sage: C is Groups().Algebras(QQ)
True
TESTS:
sage: TestSuite(GroupAlgebras(ZZ)).run()
