A helper class assembling local matrices into global multilevel matrices. This class is the multilevel equivalent of MatrixLocalBlocksToGlobalBlocks and documentation of that class applies here to a large extend.
The global matrices are expected as a vector of pointers to MatrixBlock objects, each containing a MGLevelObject with matrices with a function corresponding to SparseMatrix::add() and information on the block row and column this matrix represents in a block system.
The local matrices are a similar vector of MatrixBlock objects, but containing a FullMatrix.
If local refinement occurs, the Multigrid method needs more matrices, two for continuous elements and another two if numerical fluxes are computed on interfaces. The second set can be added using initialize_edge_flux(). Once added, the contributions in all participating matrices will be assembled from the cell and face matrices automatically.
