/**
 * This class is the graphical version of a UML Actor.
 * An ActorWidget is created by a @ref UMLView.  An ActorWidget belongs to only
 * one @ref UMLView instance.
 * When the @ref UMLView instance that this class belongs to is destroyed, the
 * ActorWidget will be automatically deleted.
 *
 * If the UMLActor class that this ActorWidget is displaying is deleted, the
 * @ref UMLView will make sure that this instance is also deleted.
 *
 * The ActorWidget class inherits from the @ref UMLWidget class which adds most
 * of the functionality to this class.
