Introduce BlockSparseMatrixData A number of algorithms like the SchurEliminator do not need access to the full BlockSparseMatrix interface. They only need read only access to the values array and the block structure. This change introduces, BlockSparseDataMatrix a struct that carries these two bits of information and modifies the Schur type algorithms to use it. What this change will allow us to do, in a subsequent CL is to take the values array of a BlockSparseMatrix and pair it with a different blocks structure for subset preconditioning.
