CHG: the toArray() function of the AbstractProcessor returns always an array now, it could be empty. But some processors await a "false" instead an empty array (ie to set falso on the sub_tree property of the parser output). This functionality has been moved into the affected processors.
CHG: some file/class comments have been corrected.
CHG: the refactored processors have now protected processXXX() methods to access others processors. This supports inheritance of the classes.
