Detailed Description

Helper class to complete the last step in a cross-array reduction.

Simply buffers a bunch of reduction messages as they arrive via subsection reductions and performs a final reduction on these to generate the final reduced message which is passed on to the client.

Note:

: Temporary entity meant to exist only until delegated cross-array reductions are implemented more optimally.
