+Tree parser for a code model.
+This is a base class which can be subclassed to create a code model "tree parser".
+Such tree parsers can be used to recursively walk through the whole code model
+or its parts and do some actions.
+
+Default implementation only walks through the model and does nothing. You need
+to reimplement necessary virtual methods of this class to add desired functionality.
