Countdown Timer

This simple class allows you to simplify project that require a countdown timer. Simply set the duration of the timer either using countdowntimer.duration or countdowntimer.duration_in_seconds and then run countdowntimer.reset(). It will then countdown from the future time - current_time + duration. Once the timer is up the isalarm variable will become True. This can be put into a simple loop such as:

c = CountDownTimer()
c.duration = 1 # minute

c.reset()
while not c.isalarm():
    c.status()
    sleep(0.25)

print("Timer is done")
