       Objects managed by the reference count

       Managed objects are objects managed by the reference count.

       There are some types of m17n objects that are managed by their reference count. Those objects are called
       managedobjects. When created, the reference count of a managed object is initialized to one. The
       m17n_object_ref() function increments the reference count of a managed object by one, and the
       m17n_object_unref() function decrements by one. A managed object is automatically freed when its
       reference count becomes zero.

       A property whose key is a managing key can have only a managed object as its value. Some functions, for
       instance msymbol_put() and mplist_put(), pay special attention to such a property.

       In addition to the predefined managed object types, users can define their own managed object types. See
       the documentation of the m17n_object() for more details.
