Class MultiLineDirectionAnnotator

java.lang.Object
  org.shapelogic.polygon.MultiLineDirectionAnnotator

All Implemented Interfaces:

Calc<Polygon>, LazyCalc<Polygon>, Improver<Polygon>, ObjectAnnotator<Polygon>

public class MultiLineDirectionAnnotator
extends java.lang.Object
implements ObjectAnnotator<Polygon>

Not this functionality is in ChainCodeHandler But this is interesting on its own, now there are no annotation going on, I need to move this in too
