def put_on_a_hat

    # set all instance variables we have in the sinatra request object
    self.instance_variables.each { |v|  @sinatra.instance_variable_set(v, self.instance_variable_get(v)) }

end

#render(template, options = {}) ⇒ Object

If a template dir is specified, use that (or don’t use one if nil is specified). Otherwise, if the controller has a default view directory, use that.
