Martijn van Groningen updated SOLR-2066:
----------------------------------------

    Attachment: SOLR-2066.patch

Updated the patch, so that is up to date with the trunk. The code compiles, but 
the test still fails.

In order to support distributed grouping properly we need a new distributed 
stage. This stage uses only the first phase collector and only retrieves the 
top groups.

All the top groups from the different shards can be merged with the utilities 
Lucene grouping module provides (GroupMerger). The groups that survive the 
merge are send to back to the shard where the came from in the next phase. 

After the merge the normal query stages kick in. But on the shard side only the 
second phase collector is used.
