# Starting with the given node, this builds a tree by recursively calling a children method.
# Takes same options as Hirb::Helper::Table.render with some additional ones below.
# ==== Options:
# [:value_method] Method to call to display as a node's value. If not given, uses :name if node
# responds to :name or defaults to :object_id.
# [:children_method] Method to call to obtain a node's children. Default is :children.
