        This example demonstrates how to manage trees

        that are saved in an XML-file

        it reads out the entire file upon calling the method

        'setup', then you can work on the tree in whichever way

        you want, just have a look at the examples

        there are different ways to achieve things,

        i will try to demonstrate (all of) them

        NOTE: for referening the XML-Nodes currently everything has to

        be lower case,

            SimpleTemplate/preFilter

        should be
