    When you view this method, it calls the *objectValues* method on
    the root folder and this shows you a simple HTML list of all the
    objects in the root folder, as shown in [3-7].

       The method objectValues(type-None) was described in API Reference Appendix B -> module ObjectManager.

       in the description, it mentions that this method accept ONE argument.
       But why in this example this doesn't accept any single element? and what is the difference?

       I must admit, I used to read JAVA API. But I'm confused reading this API reference.

       This one argument has a defaut value ("=None"), which implies in python it is optional. Magic ;-) If given,
       parameter is either one string or a list of strings, the strings the names of object meta_types to be
       filtered. If omitted, ojbectValues() gives *all* objects in the ObjectManager. Folder derives from
       ObjectManager.
