+/*************************************************** 
+  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
+  Adafruit invests time and resources providing this open source code, 
+  please support Adafruit and open-source hardware by purchasing 
+  products from Adafruit!
