//LIBRARY HOURS V2
//Created by Fred Schott Class of 2013
//Updated for Summer Hours by Dan Kass on 5/27 (added simple debugging tool too)
//
//Modified original library hours script to be more efficient and easier to update.
//Reduced Lines of Code from ~1000 to ~200
//Instead of hardcoding each date's hours into an array, v2 can handle weekly 
//   schedules as well as date exceptions, and will generate the day's operating 
//   hours dynamically.
//
//
// Format for adding Schedules:
//   KEY: X1: Start Month
//        X2:   End Month
//        Y1: Start Day
//        Y2:   End Day
//
//   Adding Exception Date: 	            
//       else if(  month==X && date==Y) { ...
//
//   Adding Schedule (Across One Month):
//       else if( (month==X && date>=Y1 && date<=Y2) {
//         switch(day) { ...
//
//   Adding Schedule (Across Multiple Months): 
//       if((month==X1 && date>=Y1) || (month>X1 && month<X2) || (month==X2 && date<=Y2)) {
//         switch(day) { ...
//
