don't overload meaning of info in Sparse Cholesky factorization functions * chol.cc (Fchol): New variable, force. Always pass natural and force to SparseCHOL and SparseComplexCHOL constructors. * SparsedbleCHOL.h, SparsedbleCHOL.cc (SparseCHOL::SparseCHOL): New arg, force. Pass it to sparse_base_chol constructor. * SparseCmplxCHOL.h, SparseCmplxCHOL.cc (SparseComplexCHOL::SparseComplexCHOL): Likewise. * sparse-base-chol.h (sparse_base_chol<>::sparse_base_chol_rep::init): * sparse-base-chol.h, sparse-base-chol.cc (sparse_base_chol<>::sparse_base_chol_rep::init): Replace nargout argument with force. Check force, not nargout > 1. * sparse-base-chol.h (sparse_base_chol::sparse_base_chol_rep::sparse_base_chol_rep): New arg, force. Pass it to init. (sparse_base_chol::sparse_base_chol): New arg force. Pass it to rep constructor.
