/// Interface to a room.
///
/// This is a lightweight object which uses a room_id and an optional event_id
/// to provide an interface to a matrix room. This object itself isn't the
/// actual room data since that takes the form of events in the database;
/// this is just a handle with aforementioned string_view's used by its member
/// functions.
///
/// This object allows the programmer to represent the room either at its
/// present state, or if an event_id is given, at the point of that event.
///
/// Many convenience functions are provided outside of this class.
/// Additionally, several sub-classes provide functionality even more specific
/// than this interface too. If a subclass is provided, for example:
/// `struct members`, such an interface may employ optimized tactics for its
/// specific task.
