Kali

Integrate with Python standard logging instead of printing directly to the console.
Also, fix the occasional bug.

The last release got some use in a real project. It was pretty quick to show off a few bugs and areas of greater need.

Added knobs for working with dates more comfortably, and updated the datebook demo to use them.

All the most important bits are in place. The roughest edges are filed down. Can I think of nice-to-have extra features? OF COURSE I CAN. So can you. Not only that, but you have what it takes to code them up, hopefully very quickly!

This is still in alpha mode, so the API could still change -- probably mostly around the template feature (which is very intentionally minimal). And definitely the future holds more complete example applications. The world would love to see what you come up with, what's comfortable, what needs more work, and why.

Now you can `pip install kali`. I have to admit it was tough giving up on the name `kale` but maybe this is better in the end.
