/**
 * Functions for editing single values
 *
 * The "DEFINE_MENU_EDIT_ITEM" macro generates the classes needed to edit a numerical value.
 *
 * The prerequisite is that in the header the type was already declared:
 *
 *   DEFINE_MENU_EDIT_ITEM_TYPE(int3, int16_t, i16tostr3rj, 1)
 *
 * For example, DEFINE_MENU_EDIT_ITEM(int3) expands into:
 *
 *   template class TMenuEditItem<MenuEditItemInfo_int3>
 *
 * You can then use one of the menu macros to present the edit interface:
 *   EDIT_ITEM(int3, MSG_SPEED, &feedrate_percentage, 10, 999)
 *
 * This expands into a more primitive menu item:
 *  _MENU_ITEM_P(int3, false, GET_TEXT(MSG_SPEED), &feedrate_percentage, 10, 999)
 *
 * ...which calls:
 *       MenuItem_int3::action(plabel, &feedrate_percentage, 10, 999)
 *       MenuItem_int3::draw(encoderLine == _thisItemNr, _lcdLineNr, plabel, &feedrate_percentage, 10, 999)
