   * <strong>ExtrusionBranch</strong> is a subclass of
   * {@link adventurejs.Extrusion|Extrusion}, with properties that allow
   * a player to {@link lasso_with|lasso} it, or
   * {@link tie_noun1_to_noun2|tie} a {@link adventurejs.Rope|Rope}
   * to it, and {@link swing_on|swing on} the tied Rope.
   * For example, you might attach an ExtrusionBranch to a
   * {@link adventurejs.Tree|Tree}, to give players a unique
   * part of the Tree to interact with.
