In order to make it easy to switch to ember-cli I'm starting changing a series
of refactorings that will prepare the codebase to the switch. Here I'm:
1. Assign all of the external objects and functions to variables in order to
make it easy to change them to imports in the feature
2. Extract functions from Travis.Helpers into local functions and create the
object at the end of file to prepare it for exporting
