24  * Standard workbench wizard for importing resources from the local file system
25  * into the workspace.
26  * <p>
27  * This class may be instantiated and used without further configuration;
28  * this class is not intended to be subclassed.

30  * <p>
31  * Example:
32  * <pre>
33  * IWizard wizard = new PreferencesImportWizard();
34  * wizard.init(workbench, selection);
35  * WizardDialog dialog = new WizardDialog(shell, wizard);
36  * dialog.open();
37  * </pre>
38  * During the call to <code>open</code>, the wizard dialog is presented to the
39  * user. When the user hits Finish, the user-selected files are imported
40  * into the workspace, the dialog closes, and the call to <code>open</code>
41  * returns.
42  * </p>
