Your transformer reminds me of FilterTransformer and Paginator 
transformer. They also divide incoming stream into blocks/pages, but 
output only one block/page at a time. I think FilterTransformer can be 
extended to include capabilities of your GroupingTransformer 
transformer, this way we will have just one transformer instead of two 
somewhat similar transformers.
