+ * Move relearner state machine
+ * ------------------------
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_FADE_TO_BLACK
+ * MoveRelearnerStateMachine: MENU_STATE_WAIT_FOR_FADE
+ *   - Go to MENU_STATE_IDLE_BATTLE_MODE
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_SETUP_BATTLE_MODE
+ * MoveRelearnerStateMachine: MENU_STATE_IDLE_BATTLE_MODE
+ *   - If the player selected a move (pressed A), go to MENU_STATE_PRINT_TEACH_MOVE_PROMPT.
+ *   - If the player cancelled (pressed B), go to MENU_STATE_PRINT_GIVE_UP_PROMPT.
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_TEACH_MOVE_PROMPT
+ * MoveRelearnerStateMachine: MENU_STATE_TEACH_MOVE_CONFIRM
+ *   - Wait for the player to confirm.
+ *   - If cancelled, go to MENU_STATE_SETUP_BATTLE_MODE.
+ *   - If confirmed and the pokemon had an empty move slot, set VAR_0x8004 to TRUE and go to
+ *     MENU_STATE_PRINT_TEXT_THEN_FANFARE.
+ *   - If confirmed and the pokemon doesn't have an empty move slot, go to
+ *     MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT.
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT
+ * MoveRelearnerStateMachine: MENU_STATE_WAIT_FOR_TRYING_TO_LEARN
+ * MoveRelearnerStateMachine: MENU_STATE_CONFIRM_DELETE_OLD_MOVE
+ *   - If the player confirms, go to MENU_STATE_PRINT_WHICH_MOVE_PROMPT.
+ *   - If the player cancels, go to MENU_STATE_PRINT_STOP_TEACHING
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_STOP_TEACHING
+ * MoveRelearnerStateMachine: MENU_STATE_WAIT_FOR_STOP_TEACHING
+ * MoveRelearnerStateMachine: MENU_STATE_CONFIRM_STOP_TEACHING
+ *   - If the player confirms, go to MENU_STATE_CHOOSE_SETUP_STATE.
+ *   - If the player cancels, go back to MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT.
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_WHICH_MOVE_PROMPT
+ * MoveRelearnerStateMachine: MENU_STATE_SHOW_MOVE_SUMMARY_SCREEN
+ *   - Go to ShowSelectMovePokemonSummaryScreen. When done, control returns to
+ *     CB2_InitLearnMoveReturnFromSelectMove.
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_DOUBLE_FANFARE_FORGOT_MOVE
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_TEXT_THEN_FANFARE
+ * MoveRelearnerStateMachine: MENU_STATE_WAIT_FOR_FANFARE
+ * MoveRelearnerStateMachine: MENU_STATE_WAIT_FOR_A_BUTTON
+ * MoveRelearnerStateMachine: MENU_STATE_FADE_AND_RETURN
+ * MoveRelearnerStateMachine: MENU_STATE_RETURN_TO_FIELD
+ *   - Clean up and go to CB2_ReturnToField.
+ * 
+ * MoveRelearnerStateMachine: MENU_STATE_PRINT_GIVE_UP_PROMPT
+ * MoveRelearnerStateMachine: MENU_STATE_GIVE_UP_CONFIRM
+ *   - If the player confirms, go to MENU_STATE_FADE_AND_RETURN, and set VAR_0x8004 to FALSE.
+ *   - If the player cancels, go to MENU_STATE_SETUP_BATTLE_MODE.
+ * 
+ * CB2_InitLearnMoveReturnFromSelectMove:
+ *   - Do most of the same stuff as CB2_InitLearnMove.
+ * MoveRelearnerStateMachine: MENU_STATE_FADE_FROM_SUMMARY_SCREEN
+ * MoveRelearnerStateMachine: MENU_STATE_TRY_OVERWRITE_MOVE
+ *   - If any of the pokemon's existing moves were chosen, overwrite the move and
+ *     go to MENU_STATE_DOUBLE_FANFARE_FORGOT_MOVE and set VAR_0x8004 to TRUE.
+ *   - If the chosen move is the one the player selected before the summary screen,
+ *     go to MENU_STATE_PRINT_STOP_TEACHING.
