/**
* Simple Reference class to handle mutable references. Handle with care!
*
* Note: In most cases, a mutable reference object like this should not be neccessary if the program is well
* structured (that's why no such class exists in the Java API).
* Extensive use of this class where it would be better to restructure the program may end in even more structural
* problems.
* Yet in some cases, a mutable reference really is needed or at least helps in creating cleaner structures.
* So again, use wisely.
