Description:
This is a modified version (see angularmod branch). It uses Angular.js to organize better the page contents. HTML regarding menus are all in a single file (templates/navigation.html), while the real content are all in the partials folder, without the code from menus.
It also loads the page contents without refreshing the whole page, thanks to Angular.js.
Please take a look at the file js/main.js. It is responsible for loading all the pages using Angular.js. It will be useful in case you want to add or remove the existing pages.
Enjoy.
