Google Dynamic DNS Tool

Easy to use cli tool that will call the google domains api and update your dynamic dns. Google Dynamic DNS can be setup here and how to do it can be read here. The tool can be used in place of having a dynamic dns application installed or set up on your router. To use this as a DynamicDNS replacement this should be setup on a cron (linux/mac) or windows task.
