rather than having each package include it directly inside of
bleve, we have decide to host them all in one repo
https://github.com/blevesearch/snowballstem
this makes the easier for the rest of the community to use
outside of bleve contexts
This change depends on the recently introduced mossStore Stats() API
in github.com/couchbase/moss 564bdbc0 commit. So, gvt for moss has
been updated as part of this change.
Most of the change involves propagating the mossStore instance (the
statsFunc callback) so that it's accessible to the KVStore.Stats()
method.
