Description
In SDR-02 paragraph 5.3.2, mentions the psSphereTransform structure contains
the sines and cosines of the angles and that these should be saved to minimize
computation time for repeated transformats. Should these calculations of the
sines and cosines occur during the constructor or upon the first transformation?

the constructor should calculate the sines and cosines.
also, it looks a bit unclear: the functions of the form
psSphereTransformICRSToEcliptic () should be constructors as well.
