org.eclipse.jface.viewers.ContentViewer
A content viewer is a model-based adapter on a widget which accesses its model by means of a content provider and a label provider.
A viewer's model consists of elements, represented by objects. A viewer defines and implements generic infrastructure for handling model input, updates, and selections in terms of elements. Input is obtained by querying an IContentProvider which returns elements. The elements themselves are not displayed directly. They are mapped to labels, containing text and/or an image, using the viewer's ILabelProvider.

Implementing a concrete content viewer typically involves the following steps:
- create SWT controls for viewer (in constructor) (optional)
- initialize SWT controls from input (inputChanged)
- define viewer-specific update methods
- support selections (setSelection, getSelection)
