-The `Select` clause indicates the attribute / aggregate value to be queried. The generic type is a `SelectResultType`, and will be used as the return type for the query.

-You can bind the return type by specializing the initializer:

-        Select<Int>(.Maximum("age"))

-/**
-The `ManagedObjectListController` monitors changes to a list of `NSManagedObject` instances. Observers that implement the `ManagedObjectListChangeObserver` protocol may then register themselves to the `ManagedObjectListController`'s `addObserver(_:)` method:
-
-    let listController = CoreStore.observeObjectList(
-        From(MyPersonEntity),
-        Where("title", isEqualTo: "Engineer"),
-        OrderBy(.Ascending("lastName"))
-    )
-    listController.addObserver(self)
-
-The `ManagedObjectListController` instance needs to be held on (retained) for as long as the list needs to be observed.
-Observers registered via `addObserver(_:)` are not retained. `ManagedObjectListController` only keeps a `weak` reference to all observers, thus keeping itself free from retain-cycles.
-
-Lists created with `observeObjectList(...)` keep a single-section list of objects, where each object can be accessed by index:
-
-    let firstPerson: MyPersonEntity = listController[0]
-
-Accessing the list with an index above the valid range will throw an exception.
-
-Creating a sectioned-list is also possible with the `observeSectionedList(...)` method:
-
-    let listController = CoreStore.observeSectionedList(
-        From(MyPersonEntity),
-        SectionedBy("age") { "Age \($0)" },
-        Where("title", isEqualTo: "Engineer"),
-        OrderBy(.Ascending("lastName"))
-    )
-    listController.addObserver(self)
-
-Objects from `ManagedObjectListController`'s created this way can be accessed either by an `NSIndexPath` or a tuple:
-
-    let indexPath = NSIndexPath(forItem: 3, inSection: 2)
-    let person1 = listController[indexPath]
-    let person2 = listController[2, 3]
-
-In the example above, both `person1` and `person2` will contain the object at section=2, index=3.
