\class NodesVisitor
\short Base class for visitors that can be used to traverse a node hierarchy.
The class follows the visitor pattern as described in Gamma et al. Pass
an instance of NodesVisitor to FolderNode::accept(): The visit methods
will be called for each node in the subtree, except for file nodes:
Access these through FolderNode::fileNodes() in visitProjectNode()
and visitoFolderNode().
*/

\method NodesVisitor::visitSessionNode(SessionNode *)
Called for the root session node.
The default implementation does nothing.

\method NodesVisitor::visitProjectNode(SessionNode *)
Called for a project node.
The default implementation does nothing.
*/

\method NodesVisitor::visitFolderNode(SessionNode *)
Called for a folder node that is _not_ a SessionNode or a ProjectNode.
The default implementation does nothing.
