def initialize_with_options(options, ordered_options)
  # Usage: 
  #  class MyClass
  #    include Meta
  #    attr_accessor :opt1, :opt2
  #    def initialize(*options)
  #      initialize_with_options(options, [:opt1, :opt2])

  #
  # obj = MyClass.new(:opt1 => 'foo', :opt2 => 'bar')
  # # OR
  # obj = MyClass.new('foo', 'bar')
  # # MyClass.new now accepts named or ordered params!
