/*
  WiFi Web Server LED Blink
 
 A UDP web server that lets you control LEDs via the net.
 Will print IP address and MAC address to the serial port
 once connected. Adapted from the SimpleWebServer and 
 WiFiUDPSendRecieveString example sketches.
 
 Recieves UDP packets, and parses them to get info for
 appropriate action. ASCII 'a' - 'y' and 'A' - 'C' are
 used in the first byte of transmitted packet to indicate
 actions or modes, and ASCII 0 - 255 are used in the second
 byte to encode light intensity values.
