Build system.

__Building the source:__

```
# After clone
$ cd build 
$ npm install grunt 
$ grunt --feature "new-feature"
$ cd ../"new-feature" # Go ahead and add what is needed.
```
This will generator the required files and also update the main `index.html`

Fixes #23

P.S : This is using raw grunt features and none of the plugins, this can be made better with something like yeoman-usemin if needed.
