Add Scatter + Gather


Add a stage to not only scatter the processing onto parallel threads, but which also allows to gather the results later on. Think of a flow which receives a directory name and is supposed to produce the number of words in all files in this directory. Such a flow could scatter word counting per file - but then would need to gather all those word counts in order to total them.
It could maybe look like this:
With the use of the CCR multi item receiver this should not be a big problem.
