/* 
  Due to an issue with babel-plugin-istanbul, we get different versions of
  coverage reports, for example:

"<...>/src/app.js": {"path":"<...>/src/app.js","statementMap":{"0":{"start"...
  vs
  "<...>/src/aws.js": {"data":{"path":"<...>/src/aws.js","statementMap":{"0":{"start"...

The difference is the added "data" key, which when present, will crash istanbul-merge
  with the error:
  Error: Invalid file coverage object, missing keys, found:data

This script loops through all our js generated coverage reports and strips
  the "data" key where present so we can merge all coverage reports into one

Currently this script is called from ~/buid/new-jenkins/js/coverage-report.sh
  which is in turn called from Jenkinsfile.coverage
