- Added parameters to the benchmark, did not rely on application generator
    - size: Size of the application, in number of method calls
    - seed: The seed to use for the random number generator for applications.
    - datastructure: The data structure to use.

This is done so that we can leverage JMH handling of parameters for running the
benchmarks.

- Added a blackhole object to avoid dead code elimination of the benchmark
  results

Changed return type of the benchmark() method to return to the blackhole object
