    ResourceClass: When the IDE creates a new unit of this type the IDE will
                   create a direct descendant from this class.
                   You should also register this class, so that, when the IDE
                   opens a unit with such a type
                   (i.e. 'TMyResouceClass1 = class(TMyResouceClass)')
                   it creates the correct class type. Just call somewhere once
                   RegisterClass(ResourceClass);
