Enables installation of Network and ObjectMapping sub-specs via CocoaPods without requiring Core Data
Add missing conditional compilation to the testing classes for use standalone from Core Data
Quiet down `AFHTTPClient` warnings when importing the Testing subspec
Fix issues with request descriptor matching and add battery of explicit tests for descriptor precedence lookup. closes #1513
Remove import of RestKit.h from RKOperationStateMachine.h
adding new ObjectManager methods for building RKObjectRequestOperation objects that take an array of response descriptors.  Updated appropriateObjectRequestOperationWithObject:method:path:parameters: to pass only the response descriptors that match the object, path, and method passed in.
Add `performBlockWithLock:` to `RKOperationStateMachine` to support changing operation state
Fix typos in exception descriptions
Return out of `cancel` if the state machine has already finished
Exposed the RKObjectRequestOperation in RKPaginator so that the developer has access to the request objects provided by the operation upon completion.
Set RKPaginator's objectRequestOperation to readonly as there is no need to set the operation for the class.
Fixed an issue where objectRequestOperations would get invalidated upon every call of loadPage even if there is a previous operation in progress. I've updated this to determine whether we've received a response from the operation instead.
Added test to determine whether an assertion is thrown while load is called while another is still processing.
Added test to determine if the objectRequestOperation is populated after loading.
Added test to determine if the objectRequestOperation from one load: is different after the next load: method is called.
Minor documentation cleanup on paginator
Use readwrite property instead of ivar when assigning an `objectRequestOperation` within the Paginator (KVO)
Merge branch 'maarek-1332-rkpaginator-exposing-rkobjectrequestoperation-new' into development
Fix issues with header layouts when using subspecs in standalone installations
Move RestKit.h inclusion to Support subspec
Conditionalize imports for RKSearchIndexer.h and RKManagedObjectStore+RKSearchAdditions.h based on Core Data import availability
Move RKSearchTokenizer to Support module as it is the only Search component that does not depend on CoreData.
