EpetraExt::BlockCrsMatrix::BlockCrsMatrix	(	const Epetra_CrsGraph &	BaseGraph,
		const std::vector< int > &	RowStencil,
		int	RowIndex,
		const Epetra_Comm &	GlobalComm
	)

BlockCrsMatrix constuctor with one block row per processor.

Creates a BlockCrsMatrix object and allocates storage.

Parameters:

	In	BaseGraph - Graph determining individual block structure, can be distrib. over subset of proc.'s
	In	RowStencil - Describes the stencil for block row on this processor (i.e. (-1 0 1) centered difference)
	In	RowIndex - Defines the index used for this block row.
