When the 'grunt demo' command is executed, it creates a child process with Endpoint.js, and establishes a connection between it and the Endpoint.js instance running on Express.js.

The child process hosts a simple API that takes input and sends a reply. You can use this instance of Endpoint.js in your browser to execute a command directly to that child process via the instance in Express.

Console messages will be output to the text box bellow. To see trace information, open the browser console.
