'''My fork of lmacken/countdown.py.

Original code was great (does what it supposed to do).

But i needed some more functionality, so there is my update of this script:

Now it accept 0 1 or 2 arguments (just ints)..

* if no argument is passed it start countdown with default 5 minutes (can be adjusted in code).
* if 1 argument is passed - than it countdown number of minutes you passed to it.
* you can pass 2 arguments - than it countdown to specific time - you have to pass hour and minute of target time...
example: python .\countdown.py 9 15  this countdown to 9:15 - you have to use 24H format :)

If less than minute - text turn red - (limit is adjustable in code)
