Created Gruntfile.js adding tasks to build Jade templates, compile sass files, and copy assets. 
There is something off with this line that I am unsure how to fix. Initially, I used the double asterisk notation ("/**") to have all files and sub-directories copy over recursively, which worked; however, it creates its' directory structure from the root level down, leaving the assets directory nested. So instead of getting "assets/images/..." you got "root/user/.../assets/images/...".
