Overriding initialize

[rstacruz]

Is there a way to subclass Hashr and provide your own initialize method? Perhaps to do validation like so:

class Config < Hashr
  def initialize(options)
    super options
    raise ConfigError, "output is not defined"  unless output?
  end
end

...or for whatever other reason the user would want to subclass Hashr. This example doesn't work properly right now.
