+
+     Implementation of rubberbands used to input corridors. There are two different modes \c InputCenterLine and \c InputBoundary. In the 
+     InputCenterLine mode the center line of the corridor has to be defined. The rubberband displays then the border geometry.
+     In the InputBoundary mode one side of the border has to be defined. The \c coordinateVector methodes always working on the input geometry.
