Squid helper handling squidguard blacklists written in python
* Only supports domains blacklists actually (ie : google.com, www.google.com, api.google.com, etc.)
* All specified blacklists are loaded in RAM
* In config specified blacklists are loaded in RAM
* Usable as an external acl plugin of squid
* Written because of poor developpement on squidguard and bad support of blacklists files using squid3
* Tested on Debian 8 / python 2.7.9

* Compatibility with python3 only
* Filters for regex urls
* Reduce memory footprint
* Code optimisation
* Code optimisation (wip)
* Use of constant database (CDB) for on-disk store : https://github.com/acg/python-cdb
* Tests
* ...
## DBs support ideas
* High performances but heavy RAM usage when using dict()
* Sqlite3 tested, light memory footprint, but very slow
* CDB to be tested, but need for speed
