Minor testing fixes.

Merge pull request #16 from DarkGhostHunter/master

Minor internal fixes for automatic testing.

Changed PHPDoc

Just a minor fix for software that reads the returns types. The make() method returns an array, or anything since this can be manipulated by a callback.

Fixed validation from RUT instance itself

As it says. In-instance validation sometimes setted as invalid Ruts instances where the vd was zero "0".

Minor fixes to the make() instantiation.

Merge pull request #13 from DarkGhostHunter/master

Minor fixes to the manual instantiation.

MInor refactoring

Merge pull request #12 from DarkGhostHunter/master

Version 2.0.1

Release 2.0

Major changes, but none too important.

Couldn't make a list of changes, but it's just better you read the README.me instead.

Fixed validation

Sometimes a RUT wasn't validated correctly. Now it does by normalizing the expected VD and the current VD of the RUT.
