coverage-badger

This is a fork of coverage-badger. Its quite slow to download from shield.io Every single time. So if there is no change to the size/color of the badge. We will just modify the %age instead. Also opens up the shieldStyle flag.

Creates a coverage badge by reading the Clover XML coverage report using https://github.com/badges/shields.

• The badge displays appropriate colors for the badge.
• Green: >= 80% overall coverage
• Yellow: 65% <= overall coverage < 80%
• Red: < 65% overall coverage
