def extend_all(nodes, *mods, &blk)
  if block_given?
    mods << NodeExtension.new(&blk)
  end

  nodes.each do |n|
    n.extend(*mods)
  end
end

#extend_parent(*mods, &blk) ⇒ Object

Extend this node’s parent. See #extend_all.

  extend_all(siblings, *mods, &blk)
end

#perform_setup! ⇒ Object

Perform setup for this node. The setup step is run after the tree has been built up completely. It allows you to perform one-time setup operations that, for example, modify the tree (like sorting blog posts into date-specific subnodes.)

Your nodes (or their extensions) may overload this method, but you may also simply use the ‘setup { … }` syntax in a node extension to define a block of code to be run at setup time.
