/**
* This sample class demonstrates how to plug-in a new workbench view. The view
* shows data obtained from the model. The sample creates a dummy model on the
* fly, but a real implementation would connect to the model available either
* in this or another plug-in (e.g. the workspace). The view is connected to
* the model using a content provider.
* <p>
* The view uses a label provider to define how model objects should be
* presented in the view. Each view can present the same model objects using
* different labels and icons, if needed. Alternatively, a single label
* provider can be shared between views in order to ensure that objects of the
* same type are presented in the same way everywhere.
