A subprogram for direct solution of Poisson equation in cylindrically symmetric geometry

A program for a direct solution of the Poisson equation in cylindrically symmetric geometry is described. It is based on the use of fast Fourier transforms for the axial solution, and an expansion in cubic B-splines for the radial solution.
