 This is an Arduino implementation of an Amazon Dash Replenishment
 device. It currently supports the critical API endpoints necessary
 for registering a device and submitting replenishment requests. This
 library is tightly coupled to the WiFi101 library, which means it will
 work great with the Arduino MKR1000, Adafruit Feather MO w/ the ATWINC1500,
 Arduino WiFi101 shiled or anywhere the WiFi library is supported. Json
 parsing is provided via ArduinoJson, thanks bblanchon!
