This patch begins a set of changes to convert the library to use JSON as the primary data type used to communicate with users; but for custom user input and output. The patch introduces the json.hpp header which is supplied by https://github.com/nlohmann/json. The header is used unmodified in the third_party directory. It is installed under the include/benchmark prefix. Additionally, this patch adds `Benchmark::WithInput` to allow the passing of arbitrary JSON as an input argument to a benchmark. The results of which can be accessed using `State::GetInput()`. This patch also adds `State::operator[](std::string)`, which allows users to report arbitrary JSON as output from a benchmark. See the documentation for examples.
