+/**
+ * A facade class which interacts with multiple DBus services to
+ * track info which is useful to the interactor's user menu:
+ *
+ *  1. A list of users to add to the user menu.
+ *
+ *     Each user is an AccountsUser object, which is a GDBusProxy
+ *     to an org.freedesktop.Accounts.User object.
+ *
+ *     We initially build this list by calling org.freedesktop.Accounts'
+ *     GetCachedUsers method. We also monitor o.f.Accounts' UserAdded
+ *     and UserDeleted and update the list accordingly.
+ *
+ *  2. Track which users currently have X sessions.
+ *     This is used for the menuitems' USER_ITEM_PROP_LOGGED_IN property.
+ *
+ *     We initially build this list by calling org.freedesktop.ConsoleKit.Seat's
+ *     GetDevices method. We also monitor the seat for SessionAdded and
+ *     SessionRemoved and update the list accordingly.
+ *
+ *  3. Provide an API for user switching and guest sessions.
+ *     These are typically pass-through functions to GDBusProxies.
