spray coffee payment web-service somewhat more complicated example

gistfile1.scala

//from https://github.com/ppurang/spray-example
//below retreive(id) always returns Option[Order]

trait CoffeePaymentService extends HttpService with LiftJsonSupport {
  self: PersistenceCoffee =>

To migrate to 1.2-M8 had to

1. use MediaType.custom instead of CustomMediaType
2. implement render for a custom header (Allow)
