> The Gelly examples use {{ParameterTool}} to parse required and optional 
> parameters. In the latter case we should detect if a user mistypes a 
> parameter name. I would like to add a {{Set<String> 
> getUnrequestedParameters()}} method returning parameter names not requested 
> by {{has}} or any of the {{get}} methods.
