first approach for test. Added PlanarRectangle test. Implemented mitk::Equal for PlanarFigure.
Implemented equals methods for each planar figure.
Renaming and refactoring new planar figure interaction test. Adding new test parameters for PlanarCircle.
Avoid VTK Warning: Hacki hack
Enhancement of the PlanarFigure equal function. Now the PolyLines and the Feature of each PlanarFigure also will be checked.
PlanarFigureInteractionTest is extended by testing the creation of Angle, BezierCurve, DoubleEllipse, FourPointAngle, Line, Polygon (closed, and not closed). Some test still fails.
