Since grunt is run from the directory where Gruntfile.js is found (using -script: 'nodejs/app.js'- to navigate into nodejs folder and find app.js), the relative paths in app.js travel upwards one folder, incorrectly searching in the folder above the fbTesting top level domain. I changed all of the paths in app.js to look in the cwd, but we need to implement a search for index.html that is agnostic to the location of the app that looks for it.
