StochGenMatrix::StochGenMatrix	(	int	id,
		long long	global_m,
		long long	global_n,
		int	A_m,
		int	A_n,
		int	A_nnz,

	)

Constructs a matrix having local A and B blocks having the sizes and number of nz specified by A_m, A_n, A_nnz and B_m, B_n, B_nnz. Also sets the global sizes to 'global_m' and 'global_n'. The 'id' parameter is used for output/debug purposes only. The matrix that will be created has no children, just local data.
