A PSR-6 cache implementation

This PSR-6 implementation is a wrapper to the phpfastcache library (http://www.phpfastcache.com/). To create a CacheItemPool you have to pass the phpfastcache configuration as constructor arguments. Using the files driver for example this will be:

$pool = new CacheItemPool(['storage' => 'files', 'path' => dirname(dirname(__DIR__)).'/.tmp/']);
