Brecht Van Lommel 4f1c674ee0 Added SuperLU 3.0:
http://crd.lbl.gov/~xiaoye/SuperLU/

This is a library to solve sparse matrix systems (type A*x=B). It is able
to solve large systems very FAST. Only the necessary parts of the library
are included to limit file size and compilation time. This means the example
files, fortran interface, test files, matlab interface, cblas library,
complex number part and build system have been left out. All (gcc) warnings
have been fixed too.

This library will be used for LSCM UV unwrapping. With this library, LSCM
unwrapping can be calculated in a split second, making the unwrapping proces
much more interactive.

Added OpenNL (Open Numerical Libary):
http://www.loria.fr/~levy/OpenNL/

OpenNL is a library to easily construct and solve sparse linear systems. We
use a stripped down version, as an interface to SuperLU.

This library was kindly given to use by Bruno Levy.
