Modern Fortran sparse linear systems solver

This is a c++ port initially performed by Luis Ibanez of the LSQR library of Chris Paige and Michael Saunders. The same methodology was applied to the LSMR library of David Fong and Michael Saunders.

This is a LSQR-CUDA implementation written by Lawrence Ayers under the supervision of Stefan Guthe of the GRIS institute at the Technische Universität Darmstadt. The LSQR library was authored Chris Paige and Michael Saunders.
