AssocLegendre class documentation

AssocLegendre is used to evaluate the associated legendre function P_l^m(x), using recursion relations from Appendix B, Volume 1, Messiah's Quantum Mechanics.

At some point I plan to make some modifications to speed up evaluation when multiple function calls are made with regularly changing values of l.

The Java version uses the doubleFactorial method from the MathLib class. For the C++ code, factorial routines are included.
