/*************************************************** 
  This is a library for the MLX90614 Temp Sensor
  Designed specifically to work with the MLX90614 sensors in the
  adafruit shop
  ----> https://www.adafruit.com/products/1748
  ----> https://www.adafruit.com/products/1749
  These sensors use I2C to communicate, 2 pins are required to  
  interface
