"""
This module is consuming the Redis-list created by the ZMQ_Sub_Curve_Q Module.

This modules update a .csv file used to draw curves representing selected
words and their occurency per day.

..note:: The channel will have the name of the file created.

..note:: Module ZMQ_Something_Q and ZMQ_Something are closely bound, always put
the same Subscriber name in both of them.


This Module is also used for term frequency.

/!\ Top set management is done in the module Curve_manage_top_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.
