# Scoped Model Driven Interceptor

An interceptor that enables scoped model-driven actions.

This interceptor only activates on actions that implement the `ScopedModelDriven` interface. If detected, it will 
retrieve the model class from the configured scope, then provide it to the Action.
  
## Parameters
 
 - `className` - The model class name.  Defaults to the class name of the object returned by the `getModel()` method.
 - `name` - The key to use when storing or retrieving the instance in a scope.  Defaults to the model class name.
 - `scope` - The scope to store and retrieve the model.  Defaults to 'request' but can also be 'session'.
