This is both faster and produces much smaller code than the old constructors
lst(ex, ex, ...) and matrix(unsigned, unsigned, lst), especially in the case
of matrices, and is now the recommended way to create these objects.
+* The function mZeta now evaluates much faster for arbitrary parameters. The
+ harmonic and multiple polylogarithms evaluate considerably faster and check
+ for convergence. The order of parameters for the harmonic polylogarithm
+ has been corrected.

* Added new symbolic functions for better integration with nestedsums:
