## Overview 

This driver controls two things called a **view** and a **spot**. 

 1. **View** - A **view** holds your content.
 2. **Spot** - Views can have blank **Spot**s where other views can be placed.

## Examples
Here is an example for the `chrome` driver of a live view built from two views.

###A note on free
If `free` is called on a view, that view is always already detached. If a *view* receives `free`, that *view* must call `free` on all of it's children before itself.
