+ *
+ * _Objects_Get_next
+ *
+ * Like _Objects_Get, but considers the 'id' as a "hint" and
+ * finds next valid one after that point.
+ * Mostly used for monitor and debug traversal of an object.
+ *
+ * Input parameters:
+ *   information - pointer to entry in table for this class
+ *   id          - object id to search for
+ *   location    - address of where to store the location
+ *   next_id     - address to store next id to try
+ *
+ * Output parameters:
+ *   returns     - address of object if local
+ *   location    - one of the following:
+ *                  OBJECTS_ERROR  - invalid object ID
+ *                  OBJECTS_REMOTE - remote object
+ *                  OBJECTS_LOCAL  - local object
+ *   next_id     - will contain a reasonable "next" id to continue traversal
+ *
+ * NOTE:
+ *      assumes can add '1' to an id to get to next index.
