Summary 0000462: IMPLEMENTED: sparse matrix improvements
Description New sparse matrix functions
* SparseGetRow() allows to read I-th row from CRS representation
* SparseConvertToHash() allows to perform in-place conversion of the sparse matrix to Hash table storage format
* SparseCopyToHash() and SparseCopyToCRS() allow to perform out-of-place conversion of the sparse matrix to another storage format
* SparseGetType(), SparseIsHash(), SparseIsCRS() functions allow to determine sparse storage type

Performance improvements:
* SparseRewriteExisting() now has O(logN) performance for CRS matrices
