@desc
The C wrapper, which calles the core Fortran routine, which
performs the actual solve.
We cannot derive the pointers to the GF data from the indeces in
Fortran. So we do this here in C and then pass the everything
over to the Fortran routine.
This wrapper is registers with the Elliptic solver registry
(not the Fortran file) , as coded up in ./CactusElliptic/EllBase

elliptic solver wrapper which provides a interface to the
different n-dimensional SOR solvers for the conformal metric,
of which only 3D is coded currently.
This wrapper is registered and if it is being called with
a n-dim. grid function, it goes of and picks the correct solver.
We pass in the arguments that are neccessary for this class of elliptic eq.
this solver is intended to solve. See ./CactusElliptic/EllBase/src/ for the
