fun is a command line application whose sole purpose is to call the icndb.com API and print a random Chuck Norris Fact to the screen.

The ICNDB allows for calls for random jokes to either include or exclude certain categories of jokes entirely, but the application has no support whatever for this functionality. Many jokes don't seem to be categorized at all, so this is a lower priority, but--with everything else now working pretty well--it'll probably be the next item on the to-do list, such as it is.
Existing command option struct has potential to add support for this.
