    Class that lets you create mock Request objects for use in testing.
    
    Usage:
    
    rf = RequestFactory()
    get_request = rf.get('/hello/')
    post_request = rf.post('/submit/', {'foo': 'bar'})
    
    This class re-uses the django.test.client.Client interface, docs here:
    http://www.djangoproject.com/documentation/testing/#the-test-client
    
    Once you have a request object you can pass it to any view function, 
    just as if that view had been hooked up using a URLconf.

        """
        Similar to parent class, but returns the request object as soon as it
        has created it.
