PHP Public Wrap: Access an object private variables and functions

PublicWrap
Set properties and methods visibility to public

This class doesn't change behaviour of your original object : it only wraps property
and method calls to make them visibles using reflection.

This is useful when you're doing unit tests on protected and private methods, or
if you want to mock a protected/private dependancy of an object.

--- Quick usage sample :

class A {
   private $x = 42;
}

Normal behaviour :

   $test = new A();
   echo $test->x; // fatal error: $x is private

With PublicWrap :

   $test = new A();
   $proxy = new PublicWrap($test);
   echo $test->x; // 42

See demo for more details (works with private and protected methods and properties).

--------- How does it work ?

PHP has magic methods:

    __get($property) let us implement the access of a $property on an object
    __set($property, $value) let us implement the assignation of a $property on an object
    __call($method, $args) let us implement a $method call

PHP has reflectiion classes:

    Reflection is a powerful tool that let us access internal constructs of classes in PHP.
