CAL's class structure is divided into three layers: Car App Service is the entry point for communication between the host and the client and is responsible for creating Sessions; a Service has a one-to-many relationship with Sessions, for example a navigation app can create one Session for the main display and one for the instrument cluster; within a Session, a stack of Screen instances is managed, and each Screen is represented by a template class and has its own lifecycle.
