+/**
+ * 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.
