+ `RKPropertyMapping` is an abstract class for describing the properties being mapped within an `RKObjectMapping` or `RKEntityMapping` object. It defines the common interface for its concrete subclasses `RKAttributeMapping` and `RKRelationshipMapping`. Each property mapping defines a single transformation from a source key path (often in the deserialized representation of a JSON or XML document) to a destination key path (typically on a target object).
