These issues has been open for some time. I have added thorough unit test coverage
for scenarios of mutating the HTTP AUTH credentials on the RKClient and on individual
RKRequest instances. Everything seems to work fine.
Also added RKAuthenticationExample to RKCatalog for testing. Needs to be updated with
support for using OAuth.
* Cleaned up remaining warnings about if (self = [super init])
* RKParamsExample - Highlights multi-part uploads
* RKRequestQueueExample - Working with the request queue
* RKBackgroundRequestExample - Examples of using the background policies for backgrounding requests
* RKReachabilityExample - Shows how to work with the reachability observer
* RKRelationshipMappingExample - Shows how to map related objects from JSON into an object graph
* RKCoreDataExample - Shows the basics of using RestKit's Core Data examples
Also rearranged dispatch of RKRequest delegate method for didStartLoad: to ensure requeue callbacks get invoked in a timely manner. refs #62
