Spline missing functions patch

Spline missing functions patch

Hi,

I've been looking at the interpolation section and I've noticed that
there are the functions
 
 - gsl_interp_name
 - gsl_interp_min_size

but no equivalents for gsl_spline.

I know it is a minor issue, but I've attached a patch adding these two
functions for gsl_spine.  Basically they are just interfaces to the
gsl_interp functions.


Cheers,

S.

Thanks for the patch, I will put that in the next release.
