New description:
Often, one wants to define a permutation group on a set other than {{{
{1,2,...,n} }}} such as say {{{ {'a', 'b', 'c', 'd'} }}}.
For example,
{{{
sage: G = PermutationGroup([ [('c','d')], [('a','c')] ])
sage: G.orbit('a')
['a', 'c', 'd']
}}}

Comment:
I had a few minutes free this afternoon, so I've done a rebased patch
myself. This is just the existing patches rebased and folded, but with the
doctest in {{{permgroup.py}}} marked as random rather than deleted, and
with examples of the output I got on a Linux and a Solaris machine.
Rob: any chance you could review this? Apologies if you'd already started
rebasing this yourself as per our earlier agreement -- in that case feel
free to ignore my patch and I'll review yours.
Leif: you might be interested to hear that this prerelease builds and
passes long doctests without problems on my 64-bit Linux machine -- no
numerical noise or anything like that.
