In the end, it probably doesn't matter.  Tho it should count up.  if I 
find something that counts down, though, I can always just do the math.

I will need to go not necessarily in order.  I might go 1,3,2,4,1,3,2, 
each shutting off the previous timer.

I'm trying to avoid writing it in python, since in the end, it'll break, 
since I'm an amateur, and the fancier it looks, the more likely I can sell 
it to professional scientists.

The stopwatch that was offered before was not appropriate, since starting 
one should stop the previous one.
