Just trying to figure out if this file needs to sit in the sizlate repo. Firstly, can't grunt-cli be installed through NPM install by adding it to the package.json? It seems strange to have two different mechanisms. Does grunt need to be global or something or is there something else im missing?

Without the  before_script  is it just setting the node version on your travis CI? Can this also not be handled in the package.json?
