27  * Standard workbench wizard that create a new file resource in the workspace.
28  * <p>
29  * This class may be instantiated and used without further configuration;
30  * this class is not intended to be subclassed.
31  * </p>
32  * <p>
33  * Example:
34  * <pre>
35  * IWorkbenchWizard wizard = new BasicNewFileResourceWizard();
36  * wizard.init(workbench, selection);
37  * WizardDialog dialog = new WizardDialog(shell, wizard);
38  * dialog.open();
39  * </pre>
40  * During the call to <code>open</code>, the wizard dialog is presented to the
41  * user. When the user hits Finish, a file resource at the user-specified
42  * workspace path is created, the dialog closes, and the call to
43  * <code>open</code> returns.
