refactored the example presentations to be in their own directory with an index.html and added an examples.html file as an index.
made the gruntfile simpler and made the watch look at all html files in all sub dirs
some small updates to the examples.html index file.
added a defer to the live reload script so that it doesn't block loading when the server isn't there.
