/**
The `Ember.ListItemView` view class renders a
[div](https://developer.mozilla.org/en/HTML/Element/div) HTML element
with `ember-list-item-view` class. It allows you to specify a custom item
handlebars template for `Ember.ListView`.
Example:
```handlebars
<script type="text/x-handlebars" data-template-name="row_item">
{{name}}
</script>
```
```javascript
App.ListView = Ember.ListView.extend({
height: 500,
rowHeight: 20,
itemViewClass: Ember.ListItemView.extend({templateName: "row_item"})
});
```
@extends Ember.View
@class ListItemView
@namespace Ember
