/**
* This interface describes a module that can be configured

* is to validate client requests and to secure responses back to the client.
*
* A module implementation must assume it may be shared
* across different requests from different clients.
* It is the module implementation's responsibility to properly
* store and restore any state necessary to associate new requests
* with previous responses. A module that does not need to do so
* may remain completely stateless.
*
*
Modules are passed a shared state Map that can be used
* to save state across a sequence of calls from validateRequest
* to secureResponse to disposeSubject.
* The same Map instance is guaranteed to be passed to all methods
* in the call sequence. Furthermore, it should be assumed that
* each call sequence is passed its own unique shared state Map instance.
