* ivi-shell supports a type of shell for In-Vehicle Infotainment system.
* In-Vehicle Infotainment system traditionally manages surfaces with global
* identification. A protocol, ivi_application, supports such a feature
* by implementing a request, ivi_application::surface_creation defined in

*
* The ivi-shell explicitly loads a module to add business logic like how to
* layout surfaces by using internal ivi-layout APIs.
