Comment (by hakre):
I've added some example code which does show this. Aditionally I've moved
the singleton logic from the meta box base class into the registry itself
in case this makes sense.
If you want to make extending classes of the base class to call the
parents constructor class you can make use of the following methodology:
* Make the base constructor final
* Make the base constructor call an init() method of the same instance.
* Make that init() method within the base class an abstract method.
Extending classes then can initialize themselves inside the init() method
instead of the constructor and must not take care any longer for
initialization of the parent class.
