-/** A Generic shape objects which is defined by a list of Outlines.
- * This Shape can be transformed to Triangulations.
- * The list of triangles generated are render-able by a Region object.
- * The triangulation produced by this Shape will define the
- * closed region defined by the outlines.
- *
- * One or more OutlineShape Object can be associated to a region
- * this is left as a high-level representation of the Objects. For
- * optimizations, flexibility requirements for future features.
- *
- * <br><br>
- * Example to creating an Outline Shape:
- * <pre>
- addVertex(...)
- addVertex(...)
- addVertex(...)
- addEnptyOutline()
- addVertex(...)
- addVertex(...)
- addVertex(...)
- * </pre>
- *
- * The above will create two outlines each with three vertices. By adding these two outlines to
- * the OutlineShape, we are stating that the combination of the two outlines represent the shape.
- * <br>
- *
- * To specify that the shape is curved at a region, the on-curve flag should be set to false
- * for the vertex that is in the middle of the curved region (if the curved region is defined by 3
- * vertices (quadratic curve).
- * <br>
- * In case the curved region is defined by 4 or more vertices the middle vertices should both have
- * the on-curve flag set to false.
- *
- * <br>Example: <br>
- * <pre>
- addVertex(0,0, true);
- addVertex(0,1, false);
- addVertex(1,1, false);
- addVertex(1,0, true);
- * </pre>
- *
- * The above snippet defines a cubic nurbs curve where (0,1 and 1,1)
- * do not belong to the final rendered shape.
- *
- * <i>Implementation Notes:</i><br>
- * <ul>
- * <li> The first vertex of any outline belonging to the shape should be on-curve</li>
- * <li> Intersections between off-curved parts of the outline is not handled</li>
- * </ul>

- * @see Region
