//Create your own custom format function to pass into cdLocalTime.displaycountdown()

//Use arguments[0] to access "Days" left

//Use arguments[1] to access "Hours" left

//Use arguments[2] to access "Minutes" left

//Use arguments[3] to access "Seconds" left

//The values of these arguments may change depending on the "baseunit" parameter of cdLocalTime.displaycountdown()

//For example, if "baseunit" is set to "hours", arguments[0] becomes meaningless and contains "n/a"

//For example, if "baseunit" is set to "minutes", arguments[0] and arguments[1] become meaningless etc

//1) Display countdown using plain text

//2) Display countdown with a stylish LCD look, and display an alert on target date/time
