GSL array functions

Hi,

Is there any chance the SpecFuncMathMore file can be expanded to call the “array” functions included in the GSL (such as gsl_sf_legendre_Pl_array)?

These functions are a bit more “dangerous” because they involve array pointers but I’ve been able to improve the efficiency of my code ~50x by using them.

The problem with them not being in root is: my code needs to be portable enough to run on various machines and the grid and getting the GSL libraries set up properly is often difficult.

Thanks for your consideration
