* This is a convenience class for those Objects which should

* LifeCycle methods defined. Extending
* NullLifeCycle reduces the required methods for the class by 5.
* Any one or two of them can be overloaded.<p>
*
* If more are overloaded, it is
* recommended just to implement LifeCycle.
* <p>
*
* This only works, though, if the Object doesn't need to extend something
* else, due to Java's Single Extension policy. In other cases, just
* implement LifeCycle, and leave them empty.
