Fuse 6.1 introduction + some amendments

* Addition of fuse introduction
* extended readme.md and 
* altered Gruntfile.js to listen on all local addresses (useful when sharing the presentation on a local N/W),  
* Also moved examples to content.
can you fix this file merge? I'd like to keep the examples directory in here. Your moving of files in examples -> content isn't a bad idea per-se but I'd rather keep examples. Also I'm not sure your change would work locally because you aren't serving up files from content.
