Automated test coverage report. (Jenkins<3Slack)

slack_coverage.py

"""
   Slack coverage.py notifier.
   
   Stewart Park <stewartpark92@gmail.com>
   
   It reports test coverage to a Slack channel as a Jenkins bot.
   Add this as a post-build/build step once coverage.py generates the html report.
   
   Once everything is properly set up, you can add a badge on your README like below:
   [![Coverage.py](http://<jenkins-host>/job/<job-name>/coveragepy/badge.svg)](http://<jenkins-host>/job/<job-name>/coveragepy/)
