Oracle for test samples

[jeandersonbc]

Create oracles based on sample apps.

It would be good to have at least some document describing expected outputs based on sample apps.

Expected output was described as JSON files for each compilation unit.
Next step is writing java objects representing these JSON objects so we can write tests to check correctness of our implementation.

To comply with our current model for registering and reporting ICC link information, we should use the ICCLinkInfo class as the layout for the JSON file. Therefore, only minor issues are needed on the JSON file, instead of sourceName, declaredPkg, and a list of intents, we should only have a list of "ICCLinkInfo", which already comprehends scope information (package+className+method) and the intent triggered by a startActivity/startService and other calls alike (see IntentInfo class).

See 7b14a6a for a quick method for comparing and diffing IntentInfo objects. @jeandersonbc
