Initial commit.

Working script.

TODO:
* Pause function.
* Write to file.
Getting somewhere.

Threading works. Pausing is bad. Input works well.
Counting now removes breaks.

TODO: Check controls and printing.
TODO: Pretty print with minutes and such.
Printing when pausing was wrong.

Reduced sleep for smoothness.
Prettier printing, better controls and help string
Now takes filename and prints to file.
