Create a best fit plane through a cloud of points.

Input parameters:

1. Pt → Points to fit.
2. Om → Method for placing plane origin.
   • 0 → Bounding Box
   • 1 → Spanning Circle
   • 2 → Average
   • 3 → Huber Centre
   • 4 → Geometric Median
   • 5 → Coordinate Median
   • 6 → Least Squareroot

Output parameters:

1. Pl → Best fit plane through all points.
2. Dv → Maximum deviation between best fit plane and furthest point.
