How to document components and models.

It'd be nice to have a recipe on the documentjs way™ to document Components and Models.

In one of our projects for example, we used the following structure for a Model (it seems `@constructor` is deprecated, since it's no longer available in the docs).

``` javascript
/**
* @page Product
* @group Product.static 0 static
* @group Product.list 1 List
* @group Product.instance 2 instance
*
* @constructor Product
* @inherits can.Model
* @parent models
* @description
* ......
**/
```

a component would look like:

``` javascript
/**
* @constructor ProductItem
* @parent components
* @group ProductItemViewModel 0 ViewModel
* @description ........
**/
```

The DocumentJS examples uses an interesting [approach](https://github.com/bitovi/documentjs/blob/f379449f4c02e2c553f749c9efc7bc247066ea2f/examples/simple/components/tabs.js#L3-L9) maybe we can come up with a more detailed example.

Start by reviewing the issue's Model and component annotation examples and the referenced DocumentJS tabs.js example. Done means proposing a detailed DocumentJS recipe that explains how to document Components and Models, including representative examples and current annotation usage.
