* <pre>
* IWizard wizard = new FileSystemExportWizard();
* 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

* are exported to the user-specified location in the local file system,
* the dialog closes, and the call to <code>open</code> returns.
