title: protractor angularJS global variables
body: <p>I'm using protractor with angularjs to create my e2e tests. I have many files for which my specs array is quite big and I want to share a common function across all files. Is there a way to create a global beforeEach of some sort where I can inject my function?
  Does the exports.config object expose something so that I can have a common variable across all files?
  Currently I'm piggy backing off the "browser" variable but that can potentially be dangerous. Any help is much appreciated. Thanks</p>
