/**
* Build a fake class dynamically that extends the desired class,
* but will act more like a Friend class on a dynamically created mock.
* This lets you use the mock methods in order to validate inputs and
* return good, simulated values.
*
* By using the class renaming functionality of Renamer, the mock is
* generated whenever you use the "new" keyword on the class we're
* changing. Please consider restructuring your code to use some sort
* of dependency injection since overriding "new" is an icky hack.
*
* Arguments for the callback, when used, should be like this:
* function ($testObject, $newMockObject, $constructorArguments)
*
* @param string $type Name of class to mock
* @param callback $callback Constructor callback for mock set up
* @param array $methodsToKeep array to pass to getMockExceptMethods
* @param boolean $callParent should the mock call the parent constructor
