In milestone 2 I completed the shell by adding the calendar (Schedule-X). There is also a meeting service that manages the current meetings based on signals, receives messages via the event bus, and sends data, for example to initialize the remotes with the active meeting. Initially the meetings are populated by a seed. On changes they are saved in LocalStorage and loaded from there again on start. In the shell there are two more Angular components: the detail view for the active meeting as well as an overview of the bus messages. The layout is three-column: calendar on the left, remotes in the middle, detail view and bus log on the right.
