Program to post message to slack messenger.
Uses slack webhook app as the entry point to posting messages. webhook-api
You will declare a default channel in slack for these messages, this can be overridden so just select something that exists.
The "url" (on line 6) will be obtained on the slack app webpage for setup of webhook app.
Enjoy!
