* Path.fromShapes can now convert any number of shapes to Path with optimzied travel distances. It internally uses Path.sortWires to minimize travel distances, and also sort wires by its Z height in case of sectioned wires. * The above python function is impelmented in Path::Area class. * Path::FeatureShape is rewrote to take advantage of these two functions. * Add Path::FeatureAreaView to partially display a Path::FeatureArea's sections.
