/**
* Request.php - Jaxon Request interface
*
* Interface for Jaxon Request plugins.
*
* Request plugins handle the registration, client script generation and processing of jaxon enabled requests.
* Each plugin should have a unique signature for both the registration and processing of requests.
* During registration, the user will specify a type which will allow the plugin to detect and handle it.
* During client script generation, the plugin will generate a <jaxon.request> stub with the prescribed call options and request signature.
* During request processing, the plugin will detect the signature generated previously and process the request accordingly.
