/**
* 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
