possible setup issue fix

Before you embark on the assignment be sure to test out running hw6runner.rb. We have had two occurrences on Windows with Ruby 2.3 which fail producing the stack trace below:

Process finished with exit code 1

If you encounter this problem try inserting the code below at the top of hw6runner.rb:

require 'tk'
require 'tkextlib/tile'
module TkItemConfigOptkeys
  def itemconfig_hash_kv(id, keys, enc_mode = [], conf = [])
    hash_kv(__conv_item_keyonly_opts(id, keys), enc_mode, conf)
  end
end
