/*
 * COMMENTS ABOUT THE startup VARIABLE -
 * Leave the startup variable blank to run as normal, enter 1 to start with the entire menu maximized. 
 * Additionally, each item can be either be displayed or not displayed in the following fashion:
 * 1|1|1|1|0|0|1|1 where 1's mean to display, and 0's mean not to display. So, in that
 * example, the first, second, third and fourth items would be displayed, the fifth and
 * sixth would not be displayed, and the seventh and eigth would be displayed on startup. Be sure
 * you set all top level items (items without submenus) to 1, or they will never be displayed!
