Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(m, *args) ⇒ Object

The hash keys are available by calling the method name “key”

h = {"profile_id" => 54, "video_id" => 12}
h.profile_id
=> 54

    self[m.to_s]
  else
    raise NoMethodError, "undefined method `#{m.to_s}' for #{self.class}"
  end
