Summary:	0000588: IMPLEMENTED: additional sparse matrix functions
Description:	New sparse linear algebra functions: * SparseTRMV - triangular matrix-vector multiply (CRS and SKS formats) * SparseTRSV - triangular solver (CRS and SKS formats) * SparseVSMV - triangular symmetric x'Ax product (CRS and SKS formats) * SparseTransposeSKS - in-place transposition of SKS matrix New informational functions: * SparseGetUpperCount() - counts symbolically non-zero strictly upper triangular elements in the matrix * SparseGetLowerCount() - same for lower triangle Improved functions: * all sparse matrix-vector and matrix-matrix functions now support SKS format
