/**
 * 
 * This GPIO provider implements the TI ADS1015 analog to digital converter chip as native Pi4J GPIO pins.
 *
 * More information about the board can be found here: *
 * http://www.ti.com/lit/ds/symlink/ads1015.pdf
 * http://adafruit.com/datasheets/ads1015.pdf
 *
 * 
 *
 * 
 * The ADS1015 is connected via I2C connection to the Raspberry Pi and provides
 * 2 GPIO pins that can be used for analog input pins.
