/*
This is a library for the BH1750FVI Digital Light Sensor
breakout board.
The board uses I2C for communication. 2 pins are required to
interface to the device.
Datasheet:
http://rohmfs.rohm.com/en/products/databook/datasheet/ic/sensor/light/bh1750fvi-e.pdf
based on Christopher Laws, March, 2013 code.
