Documentation:
The MarginView is designed to be a self contained component that manages
the display of a BBox control that shows a graphic of a page and its'
margings. The component also includes text fields that are used to mofify
the margin values and a popup to change the units used for the margins.
There are two interfaces for the MarginView component:
1) Set methods:
- page size
- orientation
Get methods to retrieve:
- margins
