This class represents a node in the tree that makes up a

Nodes are persistent data structures. Instead of changing them, you
create new ones with the content you want. Old ones keep pointing
at the old document shape. This is made cheaper by sharing
structure between the old and new data as much as possible, which a
tree shape like this (without back pointers) makes easy.
