ClassTableInheritance
=====================

 This is an ActiveRecord plugin designed to allow 
 simple multiple table (class) inheritance.
 
 This plugin was inspired by:
 inherits_from plugin => http://github.com/rwl4/inherits_from and
 Multiple Table Inheritance with ActiveRecord => http://mediumexposure.com/multiple-table-inheritance-active-record/

Example

    t.string :description, :null => false
    t.decimal :price
    t.timestamps

  create_table :book, :inherits => :product do |t|
    t.string :author, :null => false
  end
  
  create_table :videos, :inherits => :product do |t|
    t.string :year, :null => false
    t.string :genre, :null => false
  end

  # Models
