[HG] Solve for transpose (using an UMFPACK function) in uBlasLUSolver::solve(uBlasSparseMatrix. . .) rather than converting the matrix from compressed row to compressed column format. This is much faster.

Add uBlasMatrix::solve() functions and uBlasMatrix::invert to uBlasLUSolver. These functions have not yet been removed from uBlasMatrix.
