Code Coverage Report

A new code coverage report is generated every time npm test runs. Normally this coverage report is ignored by git. This project includes it in source control so the coverage report can be viewed in the demo app: http://express-app-testing-demo.herokuapp.com/coverage/lcov-report/index.html
