/***************************************************************************
This is a library for the BME680 gas, humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME680 Breakout
----> http://www.adafruit.com/products/3660
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface.
