+== Advanced Example with Nested Methods
+
+You have a VehicleModel class and the same Make class as up above:
+
+  # == Schema Information
+  #
+  # Table name: vehicle_models
+  #
+  #  id         :integer(4)      not null, primary key
+  #  name       :string(255)
+  #  year       :integer(4)
+  #  horsepower :integer(4)
+  #  price      :integer(4)
+  #  electric   :boolean(1)
+  #  make_id    :integer(4)
+  #
+
+  class VehicleModel < ActiveRecord::Base
+    belongs_to :make
+    has_csv_pirate_ship :booty => [:id, :name, :year,
+                                   {:make => :name},
+                                   {:tires => {:size => {:width => :inches}}}]
+    def tires; TireSize.new; end
+  end
+
+  class TireSize
+    # To call an instance method you need to return an instance
+    def size; TireWidth.new; end
+  end
+
+  class TireWidth
+    # To call a class method you need to return the class object
+    def width; Measurement; end
+  end
+
+  class Measurement
+    def self.inches; 13; end
+  end
+
+Then to create the CSV:
+
+  a = VehicleModel.walk_the_plank
+
+Then check the output from the console:
+
+  a.weigh_anchor
+
+  id,name,year,makename,tiressizewidthinches
+  1,Cavalier,1999,Chevrolet,13
+  2,Trailblazer,2006,Chevrolet,13
+  3,Corvette,2010,Chevrolet,13
+  4,Mustang,1976,Ford,13
+  5,Lebaron,1987,Chrysler,13
+  6,Avalon,1996,Toyota,13

+Joy to recursive code everywhere!
