.. py:function:: sort_airfoil(coords, arclen)

   
   Airfoil slices from Paraview are typically well sorted because they follow
   the curvature of the section. But, segments can be out of order. This
   function sorts these segments into counter-clockwise ordering starting
   at the top of the trailing edge.


   :Parameters:

       **coords** : ndarray
           Unsorted 2D airfoil coordinates in an X-Y plane with the flow
           direction as +X and lift direction as +Y.

       **arclen** : ndarray
           Arclengh along the segments corresponding to the input coordinates.



   :Returns:

       ndarray
           Sorted airfoil coordinates.

       ndarray
           Sorted arclength array matching the sorted airfoil coordinates.

       ndarray
           Indice mapping from unsorted to sorted coordinate array.

.. py:function:: find_te(coords)

   
   Identify trailing edge coordinates and their corresponding indices from 2D
   airfoil data in an X-Y plane.


   :Parameters:

       **coords** : ndarray
           Sorted 2D airfoil coordinates in an X-Y plane with the flow
           direction as +X and lift direction as +Y. The coordinate ordering
           should be counter-clockwise.



   :Returns:

       ndarray
           Coordinates of the upper and lower surface TE points

       ndarray
           Indices of the upper and lower surface TE points
