/**
 * Functions for editing single values
 *
 * The "DEFINE_MENU_EDIT_ITEM" macro generates the functions needed to edit a numerical value.
 *
 * The prerequisite is that in the header the type was already declared:
 *
 *   DECLARE_MENU_EDIT_TYPE(int16_t, int3, itostr3, 1)
 *
 * For example, DEFINE_MENU_EDIT_ITEM(int3) expands into these functions:
 *
 *   bool menu_item_int3::_edit();
 *   void menu_item_int3::edit(); // edit int16_t (interactively)
 *   void menu_item_int3::action_setting_edit(PGM_P const pstr, int16_t * const ptr, const int16_t minValue, const int16_t maxValue, const screenFunc_t callback = null, const bool live = false);
 *
 * You can then use one of the menu macros to present the edit interface:
 *   MENU_ITEM_EDIT(int3, MSG_SPEED, &feedrate_percentage, 10, 999)
 *
 * This expands into a more primitive menu item:
 *   MENU_ITEM_VARIANT(int3, _setting_edit, MSG_SPEED, PSTR(MSG_SPEED), &feedrate_percentage, 10, 999)
 *
 * ...which calls:
 *       menu_item_int3::action_setting_edit(PSTR(MSG_SPEED), &feedrate_percentage, 10, 999)
