+ * - All functions can be numerically evaluated with arguments in the whole complex plane. The parameters
* for Li, zeta and S must be positive integers. If you want to have an alternating Euler sum, you have
* to give the signs of the parameters as a second argument s to zeta(m,s) containing 1 and -1.
