Use a different formula to determine right-handedness

Sometimes the engine will return in FaceIsPlanar a plane which is
left-handed. But we should only be using right-handed planes. Frontend
can detect this and rotate the planes 180 degrees to ensure they're
still right-handed.

 ```
 
 Any object with appropriate `origin`, `xAxis`, and `yAxis` fields can be used as a plane.
+The plane's Z axis (i.e. which way is "up") will be the cross product X x Y. In other words,
+KCL planes follow the right-hand rule.
