/**
* Interface class for delegating tasks from CMsgMailBaseOp subclasses.
* This class is mainly needed since there exists tight coupling between
* operations and UI classes that cannot be completely loosen at the moment,
* this class allows us to delegate the difficult operation steps to another
* class (in practice to CMsgMailAppEditorUi). Due to simplicity delegation of
* all subclasses is concentrated to this one interface.
