/*
This code is provided as is, with no warranty of any kind.

I hacked it together in one night for my own use, and have not tested it extensively.

The script can slow down comment page load time; if the lag is noticeable, you may want
to change your preferences to load fewer comments per page.

Note that this runs once and does not install any persistent code on the page. So any votes
you cast will not affect the numbers displayed until you reload.

Also note that the ups and downs will not always add up to the score displayed on reddit.
I think this is because of caching on reddit's part. It's usually within one or two points though.
