    f  = File.open(file,'w')
    f.write Marshal.dump(response)
  ensure
    f.close
  end
end

.equivalent?(a, b) ⇒ Boolean

def equivalent?(a,b)
  return false if a.class != b.class
  case a
  when FlickRaw::Response,FlickRaw::ResponseList then a.methods(false).collect do |m|
      b.respond_to?(m) ? equivalent?(a.send(m),b.send(m)) : false
    end.inject(true) {|r1,r2| r1 && r2}

  when Hash then a.keys.collect  do |k|
      b.has_key?(k) ? equivalent?(a[k],b[k]) : false
    end.inject(true){|r1,r2| r1 && r2}

  when Array then a.each_with_index.collect do |v,i|
      b.length == a.length ? equivalent?(v,b[i]) : false
    end.inject(true) {|r1,r2| r1 && r2}
  else
    a == b
  end
end

.extension ⇒ Object

returns the file extension used to store the marshaled FlickRaw fixtures
