Grouper is not used in NUPIC2

@subutai said so on the ML: "The Grouper code is actually not used in the CLA.
It is an older machine learning algorithm we developed for doing temporal clustering of patterns.  "
temporal_pooler_how_to.py uses obsolete Grouper

Grouper* were removed, so this file needs to go too.
(it wasnt functional anyway)
removed TemporalPoolerNode, used obsolete Grouper

TempPoolerNode used lot of Grouper code, which is unused, so that this file couldnt
be used either. So removed.

Updated RegionImplFactory to reflect the change.
