 /**
  * Renders a view
  *
  * We now have a view name, e.g.
  * admin/stories/edit
  *
  * The algorithm to find the correct view is as follows:
  * 1. foreach registered view path $v
  *      append view name to $v
  *      glob for $v.*.*
  *      collect all candidate views
  * 2. extract distinct template types from candidate views
  * 3. run content negotiation algorithm on template types to find best fit
  * 4. find first candidate template with matching type
  * 5. derive view handler
  * 6. instantiate view handler
  * 7. render view
  *     
  * That's quite a lot of work to do.
  *
  * Possible optimisations:
  * 1. caching - keep a map of controller/view candidates
  *    (globbing is the main performance problem; would be enabled in production mode only)
  * 2. if there's only one registered template type and one handler, just assume default
  * 3. callback method can be used to selectively disable content negotiation
