Title: Remove GenCoord and GenCoordSystem

+ Remove `GenCoord` and `GenCoordSystem`
+ Compact API
+ previous API: skel->getGenCoord(index)->getPosition();
+ new API: skel->getPosition(index);
+ Performance improvement by using joint's member variable directly instead of temporary variable created by `GenCoordSystem`
