 * <p>

 * This interface is equivalent to the GM_OrientablePrimitive specified in 

 * <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=26012">ISO 19107</a>.

 * Orientable primitives are those that can be mirrored into new 

 * geometric objects in terms of their internal local coordinate 

 * systems (manifold charts).

 * </p>

 * <p>

 * For curves, the orientation reflects the direction in which the curve is traversed, 

 * that is, the sense of its parameterization. When used as boundary curves, 

 * the surface being bounded is to the "left" of the oriented curve. 

 * </p>

 * <p>

 * For surfaces, the orientation reflects from which direction the local coordinate 

 * system can be viewed as right handed, the "top" or the surface being the direction 

 * of a completing z-axis that would form a right-handed system.

 * </p>

 * <p>

 * When used as a boundary surface, the bounded solid is "below" the surface. 

 * The orientation of points and solids has no immediate geometric interpretation 

 * in 3-dimensional space.

 * </p>

 * <p> OrientablePrimitive objects are essentially references to geometric primitives 

 * that carry an "orientation" reversal flag (either "+" or "-") that determines whether 

 * this primitive agrees or disagrees with the orientation of the referenced object.

 * </p>
