Nonius 1.2.0 beta 1

This is a beta for a feature release of nonius.

Nonius is an open-source framework for benchmarking small snippets of C++ code, inspired by Criterion. Nonius runs your code, measures the time it takes to run, and then performs some statistical analyses on those measurements. Check out the documentation for more information.

This release includes several new features:

• #26 you can now call nonius::main from your main function, allowing you to do any sort of setup you want directly;
• #54 a better charts library is used for HTML reports;
• #56, #63 benchmarks can now be run with varying parameters;
• #57 there are two basic primitives to control the optimizer;
