During the processing of annotations some simple functions are needed, wich implemented for reuse in this class. Processing Annotations have achive several challenges. As first, everything is related to annotation processing need to be compiled before the code manipulation is started. For that reason, tools like loggers or template engine are just present, when this library is used as annotation processor, not for it's functionality inside. This circumstances are reasons why we have a explicit print method instead of the Logger.
