New description:
Numeric evaluation methods for the `polylog` function are commented out in
the pynac source since it tries to call the `CLN` library directly. The
calls to CLN should be replaced with their MPFR, etc. equivalents.
{{{
sage: polylog(2,1.0)
1/6*pi^2
sage: polylog(2,0.9)
polylog(2, 0.900000000000000)
