(** Process properties by creating their getters and setters in the case that they need to be syntethized *)
(** or in the case of dynamic. *)
(* How it works: *)
(* - First, the property is defined in the interface. Then, we add the method declarations of the getter *)
(* and setter to the map property_table. *)
(* - Second, in the class implementation, if synthetize is available, create the getters and setters, *)
(* unless some of these methods has already been created before. *)
