Subject: [PATCH] Clean up the example projects and codes (#512)

* Clean up Samples and Maps examples
* Rename the root view controller in Maps/Stocks/SampleObjC examples
* Reorder resource file references
* Rename examples' bundle ids with `example` domain.
* Remove 'Run Script' to modify CFBundleVersion: now this has not been used for testing since unit tests were added
* Revise methods to handle content view controllers in UseCaseController
* Fix a bug on PagePanelController
