Added Getting started example
Added Getting started example

I added some examples around initializing components due to some confusion around why dropdowns, accordions, etc do not get initialized automatically re: https://github.com/Semantic-Org/Semantic-UI/issues/1618#issuecomment-147094172
Hopefully this will cut down on the "non-issue" issues that get created for "my dropdown, toggle etc doesn't show properly..."
