Detailed Description

@abstract ThingKVOController makes Key-Value Observing simpler and safer. @discussion ThingKVOController adds support for handling key-value changes with blocks and custom actions, as well as the NSKeyValueObserving callback. Notification will never message a deallocated observer. Observer removal never throws exceptions, and observers are removed implicitly on controller deallocation. ThingKVOController is also thread safe. When used in a concurrent environment, it protects observers from possible resurrection and avoids ensuing crash. By default, the controller maintains a strong reference to objects observed.
