Targets #130

Changelog

1. Whenever a parent of a child class is directly or indirectly annotated with @State annotation, our child class will also be considered when generating benchmarks.
2. Supplimentary annotations like @Measurement @Warmup @OutputTime @BenchmarkMode are considered in this order: child -> top most annotated parent

Note: This is a phase-1 implementation, with just the basic idea laid out.

I would appreciate it if you could clarify what exactly you think should be included in phase 1.
