Added Grunt functionality for:
-js concatenation and minification
-image optimization
-css to less

imagemin is not stable, it can nuke your project images.

gitignore fixed to ignore /node_modules
it was sloppy of me to commit the dependencies folder in the first
place.

When you run grunt for the first time these dependencies are
downloaded, no need to include them in the project files.

call_user_func() expects parameter 1 to be a valid callback

I don’t know what caused this. So I grabbed a fresh version of brew and
re-added:
-Gruntfile.js
-package.json
-updated .gitignore
