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.
yeah I guess I can see why you did this as md isn't perfect - the data-fragment basically only applies to the ***fabric*** bit and not to the whole line - I've run into this myself though I think I came up with a more elegant solution.
