/**
* 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.
