I tried to make it into a gem ...

Hi Kristina,

I read your article in Code4Lib Journal today and I think you have a great idea. I wanted to tinker a bit with the script, and in that process I will probably break it up a bit into smaller pieces. To enable that I started by giving it a common gem structure, and I thought that *maybe* you would like to pull that initial change back in?

The code isn't changed at all at this point, except for one small adjustment. The script now lives in bin/access_checker (no .rb extension) and has a "shebang-line" of `#!/usr/bin/env ruby`. This makes it easy to use with rvm or any such tools. (You can still run it with "jruby -S bin/access_checker".)

I haven't released it as a gem, that must be up to you if you want to. And there is no e-mail in the gem spec, I didn't know yours or if you would like to have it public.

Please feel free to ignore this pull request - it is by no means necessary and doesn't in any way enhance your script. It only enables it to be installed with `gem install access_checker`, should you choose to publish it.
