+ * @class SortFilterRoomListModel
+ *
+ * This model sorts and filters the room list.
+ *
+ * There are numerous room sort orders available:
+ *  - Categories - sort rooms by their NeoChatRoomType and then by last activty within
+ *                 each category.
+ *  - LastActivity - sort rooms by the last active time in the room.
+ *  - Alphabetical - sort the rooms alphabetically by room name.
+ *
+ * The model can be given a filter string that will only show rooms who's name includes
+ * the text.
+ *
+ * The model can also be given an active space ID and will only show rooms within
+ * that space.
+ *
+ * All space rooms and upgraded rooms will also be filtered out.
