+This example demonstrates how to instantiate the
+Adafruit BNO055 Sensor using this library and just
+the I2C bus number.
+This example will only work on a Raspberry Pi
+and does require the i2c-gpio kernel module to be
+installed and enabled. Most Raspberry Pis will
+already have it installed, however most do not
+have it enabled. You will have to manually enable it
