-This uses the Dagger2 dependency injection framework which runs as an annotation
-processor and generates the dependency injecting code. At the moment the
-generated code for the caliper-host target can be found at:
-  out/host/common/gen/JAVA_LIBRARIES/caliper-host_intermediates/annotation_processor_output/
-For the caliper-tests target it can be found at:
-  out/host/common/gen/JAVA_LIBRARIES/caliper-tests_intermediates/annotation_processor_output/
