+ * 
+ *
+ * The returned path is a straight line there is no node widget between the source and the target node,
+ * if there are nodewidgets in between it tries to find a path around those abstacles to avoid collisions.
+ * The algorithm for the search of this path is limited by a fixed number of iterations defined in 
+ * NUMER_OF_ITERATIONS to return a result in reasonable time. If the calculation exceeds this limit the 
+ * path returned contains at least 1 collision with a nodewidget. 
+ * 
+ * This class intend to solve the same problem as the class PolyLineRouter but
+ * uses slightly different methods.
+ * + uses another algorithm for solving the collision.
+ * + the obstacle bounds are calulated in advance to avoid a recalculation.
+ * - there is no heuristic, the shortest path around the widget is choosen asap.

+/**
+ *  In comparison to the default ConnectionWidget this class is able to connect 
+ *  widgets with a curve instead of a straight line sequence. 
+ *  In conjunction with a suitable router the connection will be a straight line 
+ *  or a curve depending on the amount and the position of the controlpoints. 
+ *  Controlpoints supplied by the router, are treated as curve intersection points.
+ *  For Reflexive edges the router doesn`t necessarily need to supply 
+ *  any controlpoints, they get painted by this automatically, this can be 
+ *  excepted if the router supplys more as 2 control points for a self edge,
+ *  then the edge gets painted with the default curve interpolation algorithm.
+ *  The method used for drawing curves uses a piecewise cubic interpolation 
+ *  algorithm. Between two control points a curve is painted as cubic bezier 
+ *  curve the, inner bezier points are calculated automatically with FMILL 
+ *  tangents and a chord parametrization, this interpolant is also known as
+ *  cutmull-rom spline. The resulting spline fullfills c^1 continuity.
+ *  The the end points the interpolation algorithm uses the bessel end condition.
