    A GroupDispatcher is responsible for distributing messages (GroupMsg) within a group.

    A GroupDispatcher is responsible for distributing messages (GroupMsg) within a group. Thus, it is the central class handling a group.

    A GroupDispatcher only handles the GroupChannelActors but is not responsible for the actual joining of a study run to a group (a StudyResult to a GroupResult). This is done before creating a GroupDispatcher by the GroupAdministration, which persists all data in a GroupResult. Who is a member in a group is stored in a GroupResult.

    A GroupChannelActor is only opened after a StudyResult joined a GroupResult, which is done in the GroupAdministration. Group data (e.g., who is member) are persisted in a GroupResult entity. A GroupChannelActor is closed after the StudyResult left the group.

    A GroupChannelActor registers and unregisters itself in a GroupDispatcher.

    A new GroupDispatcher is created by the GroupDispatcherRegistry. If a GroupDispatcher has no more members, it closes itself.

    A GroupDispatcher handles all messages specified in the GroupDispatcherProtocol. There are fundamentally three different message types: 1) group session patches, 2) broadcast messages, and 3) direct messages for a particular group member.

    The group session patches are JSON Patches after RFC 6902 and used to describe changes in the group session data. The session data are stored in the GroupResult.

case class GroupMsg(json: JsObject, tellWhom: TellWhom = TellWhom.Unknown) extends Product with Serializable

Message format used for communication in the group channel between the GroupDispatcher and the group members. A GroupMsg contains a JSON node. If the JSON has an 'action' key, it is a group action message. With 'tellWhom' the recipient can be specified.
