A simple wrapper for hyper
Rhodium allows to create hyper servers as a stack of Handlers.
Each Handler has its own handle_request and handle_response methods.
Handlers are executed by order while handling a request, and by the reverse order while handling the response.
The order in which handle_request and handle_response functions are executed is summarized in the next flow diagram:

Every Handler is a struct implementing de RhodHandler trait, while the Service is a struct implementing the RhodService trait.
RhodHandlers + RhodService conforms a RhodStack
To use Rhodium, you just have to create a RhodStack, set the socket address where the hyper server will listen,
and the protocol to be used (HTTP).
If the Handler i returns an error while handling a request:
catch_request functions are called for the next handlers (Handler i+1, i+2, ..., n), and then the flow is ended.
If the Service returns an error:
the flow is ended
If the Handler i returns an error while handling a response:
catch_response functions are called for the next handlers (Handler i-1, i-2, ..., 1), and then the flow is ended.
