 NAME
    H5RC_create
 PURPOSE
    Create a reference counted object
 USAGE
    H5RC_t *H5RC_create(o,free)
        const void *o;          IN: Object to initialize ref-counted object with
        H5RC_free_func_t free;  IN: Function to call when ref-count drop to zero
 RETURNS
    Returns a pointer to a new ref-counted object on success, NULL on failure.
 DESCRIPTION
    Create a reference counted object.  The object is not duplicated, it is
    assumed to be owned by the reference counted object now and will be freed
    with the 'free' function when the reference count drops to zero.
