This module manage top sets for terms frequency.
Every 'refresh_rate' update the weekly and monthly set
Requirements
------------
*Need running Redis instances. (Redis)
*Categories files of words in /files/ need to be created
*Need the ZMQ_PubSub_Tokenize_Q Module running to be able to work properly.
