Simple IOT Clock (DOT Matrix, NTP)

# Introduction
This is a dead simple IOT clock that uses NTP to synchronize the time to UTC. It then displays the time on a cheap Dot Matrix display.

When the hour changes it displays a spiral animation.

The project uses a WiFi manager to store credentials on the ESP8266. It will start an access point name ESPXXXX when it is unable to connect to the internet. Connect to the WiFi access point and access http://192.168.4.1 to configure the WiFi credentials.
