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.
If you present to a room of people as I have done you can send them a link to your local ip on the local network. It allows participants to connect to the presentation and view it as you're viewing it. They can then click on links etc... It also allows you to use the remote control app. It took me a while to find this line so it's more for saving people time in the future
