/*
 * What you need to do:
 *  - change #includes to use your LCD/display include files
 *  - change the macros to match your LCD/display functions
 *
 * #definable options:
 *
 *   CONFIG_TINYMENU_USE_CLEAR -- clear display each time a menu is displayed
 *    (alternative fills up any menu area without entries with spaces)
 *
 *   CONFIG_TINYMENU_HAS_INVERSE -- if your display routines include inverse
 *    display functions, set this and set menu_set_inverse and menu_set_normal
 *    to call your LCD's inverse/normal functions.  Otherwise entries are
 *    all displayed in normal characters, with an asterisk before the
 *    currently "highlighted" entry.
