	 * This program is based on the work of armzilla from this github repository:
	 * https://github.com/armzilla/amazon-echo-ha-bridge
	 * 
	 * This is the main entry point to start the amazon echo bridge.
	 * 
	 * This program is using sparkjava rest server to build all the http calls. 
	 * Sparkjava is a microframework that uses Jetty webserver module to host 
	 * its' calls. This is a very compact system than using the spring frameworks
	 * that was previously used.
	 * 
	 * There is a custom upnp listener that is started to handle discovery.
