 /**
  * @brief Represents a list-like object which can have a content type.
  *
  * Example for Python:
  * @code
  *     # in the file describing the built-in list type
  *     class List:         # (1)
  *         pass
  *
  *     # in the user's code:
  *     a = []              # (2)
  *     a.append(3)         # (3)
  * @endcode
  *
  * This type class can be used to determine the type of a as "list of int" as follows:
  *     (1) When creating the type for the List class,
  *         create a ListType instead of a structure type.
  *         (Your language plugin somehow needs to know
  *         which classes are list-like; Python does this
  *         through special comments for the class)
  *     (2) Set the type of a to the type declared by the
  *         List class, as usual.
  *     (3) Call
  *         \code
  *                static_cast<ListType*>(a->abstractType())->addContentType(int_type)
  *         \endcode
  *         (Your language plugin needs to know which methods
  *         add their argument's content to the type's content;
  *         Python does this through special comments for the method)
