Evaluate and implement the datamodel edition based upon a "java code parsing library" instead of using DMO information that is based on compiled code.

The datamodeler should ideally create/modify only the java sentences he understand. e.g. create a new field, setters/getters, etc.
Java sentences not managed by the datamodeler e.g. an inner class declaration, should remain "untouched" when a .java file is edited/saved by the datamodeler.
