/**
* Object-Oriented Null (To Replace null)
*
* This file contains the null class. The null class itself doesn't equate
* to null, but it's field does, it's constant does, and function. This is
* useful when you want to return a null value that isn't actually language
* specific null because null might be a correct return type
*
* The name of this class was in conflict with a reserved keyword in PHP 7
* so it has been changed to None

* Null Class - Defines a NULL Object
*
* Some functions can return null, false, empty, etc.
* but not indicate a failure. This object gives developers a class to use
* that defines a truly null variable. This way a function could return
* null, false, empty, etc. legitimately, and upon failure return new Null;
* Example usage: if ( $loader instanceof Types\Null ) ...

* CHANGELOG

* 1.0: Created Null - May 10th, 2013
