Proposal: Expand the classic + presentational examples a little

[hmeissner]

I think it might be a bit better if we swap

return <div className='COMPONENT_NAME' />

to

return (
  <div className='COMPONENT_NAME>
    COMPONENT_NAME
  </div>
)

in the classic and presentational examples.

Most people will probably have their returns more complex than a single div so this should save some extra seconds.

Good idea man!
