/*
 * Bit Operations
 * This program is divided into tabs
 * Tabs help organize a program into pages
 * Each tab contains logically connected portions
 * of the program.
 * We are using the tabs to break down the program
 * into four different sections in addition to the 
 * main program on this tab.
 * Tabs make troubleshooting easier in that each page
 * can be looked at separately instead of trying to
 * go down a very long list on only one page.
 * In this case, three separate programs (related in that
 * they use the same LED setup and push button and all
 * are logic operations
 * 
 * Connections:
 * pin       Terminal Block
