Refactor/normalization schema

@thibaultcha I would like to merge this into 0.1.0

[thibaultcha]

Tests don't pass. #100 They do on the first commit, I'm sure it didn't need much work to polish it.

[thibaultcha]

Sounds good otherwise. But it's exactly the same as #100 and #101, you could have won 5 hours of your time lol

Test don't pass because of a moonrocks problem, not code problem:

Error: Failed installing dependency: https://rocks.moonscript.org/cassandra-0.5-4.rockspec - Failed cloning git repository.
make: *** [install] Error 1

And also because of a GitHub problem which has issues:

$ git clone --depth=50 git://github.com/Mashape/kong.git Mashape/kong
Cloning into 'Mashape/kong'...
fatal: unable to connect to github.com:
github.com[0: 192.30.252.131]: errno=Connection timed out
The command "eval git clone --depth=50 git://github.com/Mashape/kong.git Mashape/kong" failed. Retrying, 2 of 3.

Coverage increased (+1.45%) to 74.04% when pulling 0d9d80d on refactor/normalization-schema into 5e92678 on master.

Finally GitHub seems to work, tests pass.
