 /**
  * @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.
