 * Standard workbench wizard that create a new file resource in the workspace.

 * Example:
 * <pre>
 * IWorkbenchWizard wizard = new BasicNewFileResourceWizard();
 * 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, a file resource at the user-specified
 * workspace path is created, the dialog closes, and the call to
 * <code>open</code> returns.
