// Implements the Application interface, which the shell uses for basic
// communication with an application (e.g., to connect clients to services
// provided by an application). Also provides the application access to the
// Shell, which, e.g., may be used by an application to connect to other
// services.
//
// 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.
