-----------------------------------------------------------------
As Chris said above me I've been working on distributed pivot faceting. The
model had to be reworked to support this change. The new workflow is each
shards result goes into a shardRequest map, those maps are combined and
converted into a list what is what is is looked at. The combined results are
compared to each shard's and refinement requests are made. Once all the
refinement requests are made another round of refinement is queued up, this
time going one level deeper than the previous refinement requests. Because of
the nature of the system distributedprocess(rb) needed to be called from the
refinepivotfacets to actually take the enqueued refinement requests and make
them into fully fledged refinement queries. This caused some issue where other
refinment types would get recalled at their refinement identifier was never
cleared, Field facets are slightly modified to have a boolean for
"needsRefinements" and one for "wasRefined" to help distinguish.
