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

 * Example:
 * <pre>
 * IWizard wizard = new PreferencesImportWizard();
 * wizard.init(workbench, selection);
 * WizardDialog dialog = new WizardDialog(shell, wizard);
 * dialog.open();
 * </pre>
 * During the call to <code>open</code>, the wizard dialog is presented to the
 * user. When the user hits Finish, the user-selected files are imported
 * into the workspace, the dialog closes, and the call to <code>open</code>
 * returns.
