/////CUSTOM FORMAT OUTPUT FUNCTIONS BELOW//////////////////////////////
//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
