SwagProtocol

The idea for SwagProtocol was originally to facilitate prototyping custom heads for gantry systems, like 3d printers. Once a Swag device is connected to a host, the host can look up information about the device using any combination of the url {"c":"u"}, alternative url {"c":"a"}, or vocabulary {"c":"d"} provided by the Swag device, and then rock and roll! The url and alternative url are also provided by the Swag device at startup.
