29  * Standard workbench wizard for importing resources from a zip file
30  * into the workspace.
31  * <p>
32  * This class may be instantiated and used without further configuration;
33  * this class is not intended to be subclassed.
34  * </p>
35  * <p>
36  * Example:
37  * <pre>
38  * IWizard wizard = new ZipFileImportWizard();
39  * wizard.init(workbench, selection);
40  * WizardDialog dialog = new WizardDialog(shell, wizard);
41  * dialog.open();
42  * </pre>
43  * During the call to <code>open</code>, the wizard dialog is presented to the
44  * user. When the user hits Finish, the user-selected zip file is imported
45  * into the workspace, the dialog closes, and the call to <code>open</code>
46  * returns.
47  * </p>
