Launched a single Page without a routes file

[doug-wade]

One of the really interesting ideas at React Conf was a command line that could take in just a component file and would set everything up for you for rapid prototyping. I would love to be able to just point react-server-cli at a page file and have it set up a simple "/" route for that page. I could also potentially imagine pointing it at a directory and having every file named XXXPage.js being mapped to /xxx.
