* Update the CHANGELOG before releasing v0.7.0 (it is completely out of sync).

* Implement smart and transparent support for redis-cluster.

* Switch to smaller test units and add more granular tests that try to cover
  every single class.

* Documentation! The README is obviously not enought to show how to use Predis
  as it does not cover all of its features.

* Missing tests for commands:
    PUBLISH, SUBSCRIBE, UNSUBSCRIBE, PSUBSCRIBE, PUNSUBSCRIBE, DEBUG, OBJECT,
    CLIENT, CONFIG GET, CONFIG SET, CONFIG RESETSTAT, SLOWLOG, SCRIPT, PTTL,
    PSETEX, PEXPIRE, PEXPIREAT, INCRBYFLOAT, HINCRBYFLOAT
