New description:
Implement a wrapper for tables/matrices which are indexed by arbitrary
sage objects. For example, this would allow for things like
{{{
EXAMPLES::
sage: ct=CharacterTable( SymmetricGroup(5) ).display()
Character table of Symmetric group of order 5! as a permutation group

| 1a 2a 2b 3a 6a 4a 5a

X0 | 1 -1 1 1 -1 -1 1
X1 | 4 -2 0 1 1 0 -1
X2 | 5 -1 1 -1 -1 1 0
X3 | 6 0 -2 0 0 0 1
X4 | 5 1 1 -1 1 -1 0
X5 | 4 2 0 1 -1 0 -1
X6 | 1 1 1 1 1 1 1
sage: ct['X3']
[6, 0, -2, 0, 0, 0, 1]
sage: ct[3]
[6, 0, -2, 0, 0, 0, 1]
sage: ct[:,'3a']
[1, 1, -1, 0, -1, 1, 1]
