/****************************************************************************************************
RepRapFirmware - Webserver
This class serves a single-page web applications to the attached network. This page forms the user's
interface with the RepRap machine. This software interprests returned values from the page and uses it
to Generate G Codes, which it sends to the RepRap. It also collects values from the RepRap like
temperature and uses those to construct the web page.
The page itself - reprap.htm - uses Knockout.js and Jquery.js. See:
