[mpeters1]

components used: scss, assemble and modernizer

after build with components above grunt qa fails during jshint linter errors in grunfile.js and test/spec/test.js

@mpeters1 you're welcome to send a PR. We should also write a spec against this failure:

• scaffold a new project
• see if jshint passes

Can be done in .travis.yaml.

Fixed by #38.
