A wrapper for a Command function.
In order to ease life, this class may encapsulate a method of a class which in order to be used as a Command. This allows to use a member methods of a class to be called as Commands are, avoiding that the instance itself is destroyed by the EventHandler.
Because in some cases, the Command may live longer than the instance class, a boolean value indicates that the Command is "descheduled". It should be set via "deschedule" as soon as the class instance of which a method is encapsulated is destroyed and forces that the command (calling of this instace's method) is not executed.

Marks this Command as being descheduled.
A simple boolean marker ("myAmDescheduledByParent") is set which prevents this command from being executed.
