+/** 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>
