> The {{mapChildren}} method in the {{TreeNode}} class is commonly used. In
> this method, there's a if statement checking non-empty children. However,
> there's a cached lazy val {{containsChild}}, which avoids unnecessary
> computation since this {{containsChild}} is used in other methods anyway.
