    Description

      In order to allow the FsImageValidation tool to verify the namespace structure, we use a visitor pattern so that the tool can visit all the INodes and all the snapshots in the namespace tree.

      The existing INode.dumpTreeRecursively() can also be implemented by a visitor.
