def self.included(base)
  #this overrides the 'new' method in any class including Ordering -- then when called, new overrides the 'order' method
  #overriding is not a simple matter in Ruby because includes put the modules below the class in the superclass sequence
  #this keeps the code cleaner by avoiding alias_method_chain (monkey patching)
  (class << base; self; end).send(:include, ClassOverrideMethods)
