geturl.el --- Insert the URL of the 'topmost' web browser

geturl.el provides a simple command that will insert the URL of the "topmost" instance of your web browser of choice.

Note that, at the moment, this only works on macOS. I seldom work for any sensible time in any other environment so adding other platforms isn't a priority right at the moment. The code is, however, written in a way that it would be simple enough to extend.
