Started to implement async stream client call
Disconnecting streaming clients in case of error
Added more Streaming data
Removed printouts
Furter streaming components implemented
Suggestions queries now have to send an AnalyticsData object storing user session ID and user-agent information
Implemented AnalyticsLogger
Now using long as ID of suggestions fields, and payload value and ID of
the payload in the corresponding index
generateSuggestionsFromESResponse now gets the payload via concurrent
requests
Formatted
If we store the payload as is we get the following exception. Now the
payload is stored in a json field.

Bug in rebase fixed
further rebasing
Bugfix: generateSuggestionsFromESResponse has called callback.onComplete
twice
Moved checks from SuggestionIndexTest into reusable methods
fixed #2 by splitting a bulk import into several bulkRequests
Bugfix: If a suggestion list was empty the callback was not called
Merged SeparatePayloadStore branch into develop
