+				Given a set of input vectors, a zonohedron is defined
+				as the convex hull of all the points which can be costructed by summing

+				The surface closing this solid is composed only of flat parallelograms,

+				It is always point-symmetric.

+				Mesh created by this class are pure-quad meshes (triangular bit-quad),

 					1) Instantiate a Zonohedron.
