Generic interface for sparse LU solver.
This generic interface (common to several sparse solvers), allow to interchange solver solutions when dealing with sparse linear systems. See itk::ParameterizationQuadEdgeMeshFilter for reference.
It internally uses the VNL library to represent and deal with vectors (vnl_vector) and sparse matrices (vnl_sparse_matrix). The solver by itself is made of a sparse LU decomposition followed by solving upper triangular system. see vnl_sparse_lu for more details on the method used.
