Find the illumination angles (phase, incidence, and 
emission) at a specified surface point of a target body. 

The surface of the target body may be represented by a triaxial 
ellipsoid or by topographic data provided by DSK files. 

The illumination source is a specified ephemeris object.
param method: Computation method.
