ECIToSunEathRot:

--------------------------------------------------------------------------
   Convert ECI to Sun Earth rotating coordinates about the barycenter.
   The coordinate frame is +x pointing at the Earth along
   the Sun-Earth line. +z normal to the Sun-Earth (ecliptic) plane
   and +y completing the set. Uses SunV1. Computes the plane
   by looking at the sun vector at jD(k) and then 1 day later.

   Type
