""" This is a simple stop watch displayed on a Tkinter canvas.
It is given a size (diameter in pixel), a maxTime (this is how long it will take the hand
to go round the clock once; after that the clock stops, the clock's face becomes red and
'time is over'), and a function that is called when time is over.
The clock is started with Clock.start; it can be stopped with the Clock.stop function
(returns the elapsed time) and reset with Clock.reset.
The maxTime can be changed with the changeMaxTime function; it makes a new window with
a scale pop up, where the time in seconds can be chosen.
When the clock is running, the system clock is checked every 100 milliseconds, but the
clock hand is updated only once a second.
