A lab for testing and demonstrating Asciidoctor extensions. Please do not use this code in production. If you want to use one of these extensions in your application, create a new project, import the code, and distribute it as a RubyGem. You can then request to make it a top-level project under the Asciidoctor organization.
This extension was inserting the older "Classic" tracking code but Google now strongly recommend to use their "Universal Analytics" tracking code.
