This is a Liquid Filter that will display the domain name of a URL.
This was originally developed for use with Jekyll, to register it as a plugin,
copy _plugins/domain_name.filter.rb to your _plugins directory.
If you had a variable such as page.url then you could put {{ page.url|domain_name }} in your text
and it would strip any http:// part and the path from the url, leaving you just the domain name.
