UDPLogger

A simple UDP logger that lets you send messages via UDP to a remote host. It's a cheap implementation for logging to a remove host via UDP. Note, the logger is uses UDP sockets provided by NetServices (https://mbed.org/cookbook/NetServices). After you are ready with the network setup (eth.setup()...), just call Log::init(), so the logger would create its local socket, and then you can log any text via Log::log(); Also note that the logger won't do any net polls (eth.poll()) to save computing tim
