Class implementing logical layer for interactive dragging of annotation labels. It includes two components: listener for GUI events occuring inside of OCCT 3D viewer and processor for hooked events to perform interactive modification of the selected annotation within current AIS context.

It handles the events coming to viewport and identifies whether the events can invoke an interaction operation or not. If yes, the operation is performed within the interactor class and events are "accepted". Otherwise, the events are passed to viewer's subroutines.
