Advanced A+ES with domain services

gistfile1.cs

// This is slightly advanced usage scenario of Lokad A+ES tests, that shows
// setting up test implementations of domain services in ES+friendly way 
// (really simple) that also prints out in the specifications. Price is an 
// instance of IPricingService, used by Application service, while Clock 
// is a static singleton actually.
