-This is a simple implementation of multicast DNS query support for an Arduino
-running on ESP32 chip. 
-
-Usage:
-- Include the ESP32 Multicast DNS library in the sketch.
-- Call the begin method in the sketch's setup and provide a domain name (without
-  the '.local' suffix, i.e. just provide 'foo' to resolve 'foo.local'), and the
-  Adafruit CC3000 class instance.  Optionally provide a time to live (in seconds)
-  for the DNS record--the default is 1 hour.
-- Call the update method in each iteration of the sketch's loop function.
