Contributed by Joshua R English, adapted by Oliver Schoenborn to be
consistent with pubsub API.

An extension for pubsub (http://pubsub.sourceforge.net) so topic tree
specification can be encoded in XML format rather than pubsub's default
Python nested class format.

To use:

    xml = '''
        <topicdefntree>
        <description>Test showing topic hierarchy and inheritance</description>
        <topic id="parent">
            <description>Parent with a parameter and subtopics</description>
            <listenerspec>
                <arg id="name" optional="true">given name</arg>
                <arg id="lastname">surname</arg>
            </listenerspec>

            <topic id="child">
                <description>This is the first child</description>
                <listenerspec>
                    <arg id="nick">A nickname</arg>
                </listenerspec>
            </topic>
        </topic>
        </topicdefntree>
    '''

These topic definitions are loaded through an XmlTopicDefnProvider:

    pub.addTopicDefnProvider( XmlTopicDefnProvider(xml) )

The XmlTopicDefnProvider also accepts a filename instead of XML string:

    provider = XmlTopicDefnProvider("path/to/XMLfile.xml", TOPIC_TREE_FROM_FILE)
    pub.addTopicDefnProvider( provider )

Topics can be exported to an XML file using the exportTopicTreeSpecXml function.
This will create a text file for the XML and return the string representation
of the XML tree.
