The console/config node tree is the central data-structure of the library. Into this tree, all
commands and parameters are entered. The tree is then exposed using a file-system like

corresponding senf::console::DirectoryNode::add() overload.

When directly adding a node callback, the type of node added depends on the type of
callback. The callback types which can be added are listed at \ref console_callbacks.
