trait ActionRefiner[-R[_], +P[_]] extends ActionFunction[R, P]
A simple kind of ActionFunction which, given a request (of type R), may either immediately produce a Result (for example, an error), or call its Action block with a parameter (of type P). The critical (abstract) function is refine.

refine[A](request: R[A]): Future[Either[Result, P[A]]]
Determine how to process a request.
Determine how to process a request. This is the main method than an ActionRefiner has to implement. It can decide to immediately intercept the request and return a Result (Left), or continue processing with a new parameter of type P (Right).
- request
the input request
- returns
Either a result or a new parameter to pass to the Action block

Invoke the block.
Invoke the block. This is the main method that an ActionBuilder has to implement, at this stage it can wrap it in any other actions, modify the request object or potentially use a different class to represent the request.
- request
The request
- block
The block of code to invoke
