-  '''
-  Determine angle of incidence from surface tilt/azimuth and apparent sun zenith/azimuth 
-
-  The surface is defined by its tilt angle from horizontal and its azimuth pointing angle. 
-  The sun position is defined by the apparent (refraction corrected)sun zenith angle and the sun 
-  azimuth angle.
-
-  Parameters
-  ----------
-  SurfTilt :  scalar or DataFrame of surface tilt angles in decimal degrees
-
-               If SurfTilt is a DataFrame it must be of the same size as all other DataFrame
-               inputs. SurfTilt must be >=0 and <=180. The tilt angle is defined as
-               degrees from horizontal (e.g. surface facing up = 0, surface facing
-               horizon = 90)
-
-  SurfAz :  scalar or DataFrame of the surface azimuth angles in decimal degrees
-
-               If SurfAz is a DataFrame it must be of the same size as all other DataFrame
-               inputs. SurfAz must be >=0 and <=360. The Azimuth convention is defined
-               as degrees east of north (e.g. North = 0, East = 90, West = 270).
-
-  SunZen : scalar or DataFrame of apparent (refraction-corrected) zenith angles in decimal degrees. 
-
-               If SunZen is a DataFrame it must be of the same size as all other DataFrame 
-               inputs. SunZen must be >=0 and <=180.
-
-  SunAz : scalar or DataFrame of sun azimuth angles in decimal degrees
-
-               If SunAz is a DataFrame it must be of the same size as all other DataFrame
-               inputs. SunAz must be >=0 and <=360. The Azimuth convention is defined
-               as degrees east of north (e.g. North = 0, East = 90, West = 270).

-  Returns
-  -------
-  AOI : DataFrame
-      The angle, in decimal degrees, between the surface normal DataFrame and the sun beam DataFrame.
