+/// Defines an interface equivalent to a 2D array of TObject, indexed
+/// by a pair of integers (somehow a matrix, 
+/// except that indices are not necessarily sequential).
+/// 
+/// It's extremely simple and hopefully allow many implementations.
+/// It also makes the object ownership self-evident.
