ActsAsList
==========

This acts_as extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a +position+ column defined as an integer on the mapped database table.
Unlike standard rails acts_as_list plugin from which it has been forked, this plugin can do one little thing more


Example
=======

  class TodoList < ActiveRecord::Base
    has_many :todo_items, :order => "position"
  end

  class TodoItem < ActiveRecord::Base
    belongs_to :todo_list
    acts_as_list :scope => :todo_list
  end

  todo_list.first.move_to_bottom
  todo_list.last.move_higher


And surprise ^^
===============

Moving 

    todo_list.first.move_lower(2)


-- Todo 1 --      --\       -- Todo 2 --
-- Todo 2 --         \      -- Todo 3 --
-- Todo 3 --          \--   -- Todo 1 --
-- Todo 4 --                -- Todo 4 --
