renamed "source" folder to mixins
updated .gitignore with node_moduls
ignoring notes file
code comments and minor formatting. also started adding basic LESS mixins temporarily. once this file is converted to LESS entirely we will use Bootstrap's mixins and externallize the rest of the custom mixins.
removed junk that I was testing
cleaning up to start converting CSS animations to LESS mixins.
removing minified CSS until it's actually usable
index.html to demo LESS animations. not working yet.
