The PETScSparseMatrixInfo provides access to the MatInfo struct of a matrix from PETSc. It is a child of the SparseMatrixInfo class. Maybe we want to implement a similar object for Trilinos? The PETScSparseMatrix class has a corresponding new getInfo() method and we can insert a PETScSparseMatrixInfo into the output stream. ElementwiseOperatoPetscTest now uses this new approach for its reporting. Further changes in PETScSparseMatrix: * renames assemble to assemble_ * make constructor set assemble_ to false * relocates setting assemble_ to true from createMatrixFromOperatorOnce() to createMatrixFromOperator(), so that we can sensibly query it in getInfo()
