//#################### Plugin 050 I2C TCS34725 RGB Color Sensor with IR filter and White LED ############
//#######################################################################################################
//
// RGB Color Sensor with IR filter and White LED
// like this one: https://www.adafruit.com/products/1334
// based on this library: https://github.com/adafruit/Adafruit_TCS34725
// this code is based on 20170331 date version of the above library
// this code is UNTESTED, because my TCS34725 sensor is still not shipped :(
