"""Represents the base Node type, demonstrating the methods to override.
:meth:`__str__` must be overridden. It should return a ``str``
representation of the node. If the node contains :class:`.Wikicode`
objects inside of it, :meth:`__children__` should be a generator that
iterates over them. If the node is printable (shown when the page is
rendered), :meth:`__strip__` should return its printable version,
stripping out any formatting marks. It does not have to return a string,
but something that can be converted to a string with ``str()``. Finally,
:meth:`__showtree__` can be overridden to build a nice tree representation
of the node, if desired, for :meth:`~.Wikicode.get_tree`.
