/**
*
* Note: uses @Typed to limit the types it is available for injection to just ModelProcessor.
*
* This is because the ModelProcessor interface extends ModelLocator and ModelReader. If we
* made this component available under all its interfaces then it could end up being injected
* into itself leading to a stack overflow.
*
* A side-effect of using @Typed is that it translates to explicit bindings in the container.
* So instead of binding the component under a 'wildcard' key it is now bound with an explicit
* key. Since this is a default component this will be a plain binding of ModelProcessor to
* this implementation type, ie. no hint/name.
*
* This leads to a second side-effect in that any @Inject request for just ModelProcessor in
* the same injector is immediately matched to this explicit binding, which means extensions
* cannot override this binding. This is because the lookup is always short-circuited in this
* specific situation (plain @Inject request, and plain explicit binding for the same type.)
*
* The simplest solution is to use a custom @Named here so it isn't bound under the plain key.
* This is only necessary for default components using @Typed that want to support overriding.
*
* As a non-default component this now gets a negative priority relative to other implementations
* of the same interface. Since we want to allow overriding this doesn't matter in this case.
* (if it did we could add @Priority of 0 to match the priority given to default components.)
