Allow processing of custom class-level and field-level annotations

 Description  « Hide
Currently, in order to add a custom field-based annotation you need to create a custom class annotation and then implement an AnnotationReader that is associated with the class annotation. I'd like to be able to add a custom field annotation while reusing the existing AnnotationReader implementations. This isn't critical because I can use @Extension to achieve the same goal, but it's definitely a nice-to-have.

Far better way is to provide a plugin-point for users to define handlers for class-level and field-level annotations and then call these when processing the annotations in the AnnotationReader. This then provides a hook allowing updates to the AbstractClassMetaData, AbstractMemberMetaData objects by user code.

SVN trunk adds extension points
