    tdf#128463: Make SetCellColor python example actually do sth
    
    The previous one, when run from within the application, gives a
    runtime exception.
    
    This commit rewrites this example to:
    1. Hide the private function from the UI;
    2. Create a new blank Calc file instead of operating directly in the existing file;
    3. Set cell colors to draw a "LO" picture in the sheet.
    4. Added docstrings and API reference links.
