Added initial text for "views" page.

Change whatever you think needs some changing, especially around the text for "partials" and "best practices".  I left out a guide for what markup looks like with ejs and jade, since there are a lot of resources for that out there.

Also, from previous experience in the Rails world, I have always referred to _includes_ as _partials_, and I'm still confused as to what we should call them in Node....
