Simple implementation of CTS verifier as a library.

Note that we included all CTS verifier classes and functions in here. Library will be at
out/target/common/obj/JAVA_LIBRARIES/cts-verifier-facilities_intermediates/{*.jar}.
It's a starting point (or proof of concept). When time permissible, we can then filter out
un-necessary test cases from this library. We can also just merge this in for now.
