o the user.

Lets demonstrate this using the example tree presented thus far. Lets assume we append this to the above example:
\code
QString fileName = QApplication::applicationDirPath() + "/example_tree.xml";

// Save the tree to a file:
rootNode->saveToFile(fileName);

// Load the tree from a file:
rootNode->loadFromFile(fileName);

// Or add the node produced from a file as a child to a node:
rootNode->addNodeFromFile(fileName);
\endcode

The format of the output tree is defined by Qtilities::ExportVersi
