Class
RequestTransformer
Translate and transform from PSR7 requests into CakePHP requests.
This is an important step for maintaining backwards compatibility with existing CakePHP applications, which depend on the CakePHP request object.
There is no reverse transform as the 'application' cannot return a mutated request object.
