New description:

 Probably just another symbolic function would suffice. This would be
 needed for zeta expansion and special values. The Sage side would be a new
 `GinacFunction` and numeric evaluation. Section 4.2 of
 http://arxiv.org/abs/1309.2877 would be the starting point of the latter.

 Depends on https://github.com/pynac/pynac/issues/120
