/**
* Analyze controller return value and send appropriate headers such as 404, 302, 301, redirect to internal routes.
*
* <p>It is very SEO friendly but you would need to know the basics of HTTP status code.</p>
* <p>Automatically handles 404, include error document or redirect to inner route
* to handle the error based on config <b>ERROR_404_DOCUMENT</b> and <b>ERROR_404_ROUTE</b></p>
* <p>Controller return value examples:</p>
* <code>
* 404 #send 404 header
* array('/internal/route', 404) #send 404 header & redirect to an internal route
* 'http://www.google.com' #redirect to URL. default 302 Found sent
* array('http://www.google.com',301) #redirect to URL. forced 301 Moved Permenantly sent
* array('/hello/sayhi', 'internal') #redirect internally, 200 OK
* </code>
