Fine-grained configuration options through annotations or tags

[sjoerdtalsma]

The Usage page of UMLDoclet version 1 is huge and full of many 'fine grained' settings that blur the overall configuration settings that you actually might care about.

Therefore it would be beneficial to have a more fine-grained way to tune UML rendering options, possibly even from the code-level. I think there are basically two strategies to pick from:

1. Javadoc Tags
2. Annotations

Either may can be applied on field, method, class, package level, so inherently offer better granularity of configuration.

Maybe experiment with e.g. #124 as a proof of concept how to implement this.
