// Description:
//
//      Clock defines a "clock" class in which each object represents
//      a clock able to display time in hh:mm:ss (am/pm) format.
//
// Usage:
//
//      See method definitions for usage of individual methods.
//
//      main() tests the other methods:
//      "java Clock hh mm ss ampm n" does the following:
//              creates a Clock object c with initial time set to 
//                      hh:mm:ss (am if ampm = "am", pm if ampm = "pm").
//              invokes showClock() on c to display initial time.
//              invokes tickClock() and then showClock() on c, n times.
//              invokes resetClock(hh, mm, ss, ap) and showClock() on c.
//      (It is assumed that 5 arguments are provided, and that hh, ss,
//              mm, and n represent integers.)
//      examples:
//              "java Clock 11 59 59 am 10"
//              produces the following output:
//                      11:59:59 am
//                      12:00:00 pm
//                      12:00:01 pm
//                      12:00:02 pm
//                      12:00:03 pm
//                      12:00:04 pm
//                      12:00:05 pm
//                      12:00:06 pm
//                      12:00:07 pm
//                      12:00:08 pm
//                      12:00:09 pm
//                      Resetting clock to initial time.
//                      11:59:59 am
//              "java Clock 20 0 0 am 10"
//              produces the following output:
//                      Invalid input; setting to default values.
//                      12:00:00 am
//                      12:00:01 am
//                      12:00:02 am
//                      12:00:03 am
//                      12:00:04 am
//                      12:00:05 am
//                      12:00:06 am
//                      12:00:07 am
//                      12:00:08 am
//                      12:00:09 am
//                      12:00:10 am
//                      Resetting clock to initial time.
//                      Invalid input; setting to default values.
