+Converts the cartesian product of two zonotopes to a new zonotope.
+
+### Input
+
+- `Zonotope` -- type used for dispatch
+- `S`        -- cartesian product of two zonotopes
+
+### Output
+
+A zonotope.
+
+### Algorithm
+
+The cartesian product is obtained by:
+
+- Concatenating the centers of each input zonotope.
+- Arranging the generators in block-diagional fashion, and filled with zeros
+  in the off-diagonal; for this reason, the generator matrix of the returned
+  zonotope is built as a sparse matrix.
