Allows re-running of protractor tests based on xunit result files.

Credit to Yahoo Protractor-retry for inspiration. I borrowed several design choices from this repo.

Will re-run tests and modify xunit result files with successes on-the-fly.

var retry = new (require('protractor-xunit-retry'))('./path-to-your-xunit-files');

In your protractor-config file

afterLaunch: () => {
  retry.afterLaunch(maxRetryAttempts);
}
