"""
The ZMQ_Sub_Onion Module
============================
This module is consuming the Redis-list created by the ZMQ_Sub_Onion_Q Module.
It trying to extract url from paste and returning only ones which are tor
related (.onion)
..seealso:: Paste method (get_regex)
..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. (Redis)
*Need the ZMQ_Sub_Onion_Q Module running to be able to work properly.
