Functions
int	lsst::sphgeom::orientationExact (Vector3d const &a, Vector3d const &b, Vector3d const &c)
	orientationExact computes and returns the orientations of 3 vectors a, b and c, which need not be normalized but are assumed to have finite components.
int	lsst::sphgeom::orientation (UnitVector3d const &a, UnitVector3d const &b, UnitVector3d const &c)
	orientation computes and returns the orientations of 3 unit vectors a, b and c.
int	lsst::sphgeom::orientationX (UnitVector3d const &b, UnitVector3d const &c)
	orientationX(b, c) is equivalent to orientation(UnitVector3d::X(), b, c).
int	lsst::sphgeom::orientationY (UnitVector3d const &b, UnitVector3d const &c)
	orientationY(b, c) is equivalent to orientation(UnitVector3d::Y(), b, c).
int	lsst::sphgeom::orientationZ (UnitVector3d const &b, UnitVector3d const &c)
	orientationZ(b, c) is equivalent to orientation(UnitVector3d::Z(), b, c).
