qs82d

[savenko]

Here I have several programs that I hope might be useful to the others.
Brian Gough proposed to mail them here for the people to look at. The
programs are: 
Sf_bessel_z.zip - spherical bessel functions of integer order of complex
argument. 
Qs82d.zip - multidimensional integration routine translated from
compliance of the library holders from
http://www.srcc.msu.su/num_anal/lib_na/cat/q_f/qs82d.zip
Matrix_interpolation - simple routine that interpolates the square
array.

Any comments and suggestions are appreciated.
