"""
The ZMQ_Sub_Attribute Module
============================
This module is consuming the Redis-list created by the ZMQ_PubSub_Line_Q Module.
It perform a sorting on the line's length and publish/forward them to differents
channels:
*Channel 1 if max length(line) < max
*Channel 2 if max length(line) > max
The collected informations about the processed pastes
(number of lines and maximum length line) are stored in Redis.
..note:: Module ZMQ_Something_Q and ZMQ_Something are closely bound, always put
the same Subscriber name in both of them.
Requirements
------------
*Need running Redis instances. (LevelDB & Redis)
*Need the ZMQ_PubSub_Line_Q Module running to be able to work properly.
