Deleted testExample method in NTDCoreDataTableViewControllerTests.
Test Frc’s performFetch is called when SUT’s performFetch is called.

When Sut’s fetchedResultsController is not nil, and its performFetch is called,
its fetchedResultsController’s performFetch method should be called.
Added Prefix header.
Added code and fake objects to pass the test.
Test if tableView’s method reloadData is called when Sut’s performFetch is called.
Code and fake object to pass the test.
Test if Frc’s fetch fails then sut’s log is called.
Code to pass the test.
Renamed test to testSutWillLogFailureIfFRCsFetchFailed.
Test Sut logs error which occurs during FRC is fetching.
Code to pass the test.
Test Sut’s performFetch method is called after creating new FRC.
Minor change.
Last commit was wrong. Oops.
Deleted last test.

Because Sut’s performFetch method can not be called in the getter of Sut’s fetchedResultsController.
This will cause these two methods calling each other resulting in a infinite loop.
Added documentation for performFetch method.
Release 0.0.4.
