// .NAME vtkMultiBlockMergeFilter - merges multiblock inputs into a single multiblock output
// .SECTION Description
// vtkMultiBlockMergeFilter is an M to 1 filter similar to
// vtkMultiBlockDataGroupFilter. However where as that class creates N groups
// in the output for N inputs, this creates 1 group in the output with N
// datasets inside it. In actuality if the inputs have M blocks, this will
// produce M blocks, each of which has N datasets. Inside the merged group,
// the i'th data set comes from the i'th data set in the i'th input.
