this is a simple form initializer that is ALMOST compatible with Bootstrap3 apart from a way to set the class of the label this would work perfectly

HAML Partials wihout Rails (useful for LiveReload)
/ A simplistic way of loading and rendering HAML partials (header.haml, footer.haml, nav.haml... you name it) without Rails
/ Useful when using tools like LiveReload http://livereload.com/
/ but don't want to configure a web server just to use PHP include/require constructs (discussion http://help.livereload.com/discussions/questions/22-haml-partials)
/ It could be improved/simplified using a helper http://stackoverflow.com/questions/5436769/partial-haml-templating-in-ruby-without-rails/5436973#5436973
/ Check out the Jade version https://gist.github.com/2593727
