// Typically, you create one or more classes implementing your APIs (e.g.,
// FooImpl implementing Foo). See bindings/binding.h for more information. Then
// you implement an mojo::ApplicationDelegate whose
// ConfigureIncomingConnection() adds services to each connection. Finally, you
// instantiate your delegate and pass it to an ApplicationRunner, which will
// create the ApplicationImpl and then run a message (or run) loop.
