* inline performance critical code * Average runtime is specified and used to calculate iterations. * Console: show median of multiple runs * plot: show box plot * filter benchmarks * specify scaling factor * ignore src/test and src/bench in command line check script * number of iterations instead of time * Replaced runtime in BENCHMARK makro number of iterations. * Added -? to bench_bitcoin * Benchmark plotly.js URL, width, height can be customized * Fixed incorrect precision warning
