Backbone: What is the recommand way to nest views?
===

I would like to know what is the recommaned way of nesting Backbone Views.

Possible ways to nest views:

1. Render all views and put them together in the Router
2. Let an IndexView do all the nesting which is called in the router
3. Include views in underscore templates

I tried my luck already in this fiddle: http://jsfiddle.net/m48Nc/2/

*Annotation*: I know that the example doesn't work it just shows the structure, I figured out currently, but am not happy about it.

So which way is to go? Links are also welcome ;)
