/**
 * 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
     * 2.0: Reproduced Null for Primus - April 2nd, 2015
     * 3.0: Formatted Null for inclusion in phabstractic
     * Changed classname to None - July 7th, 2016
     *
     * @version 3.0
