Random Number Generator C++ Wrapper

Wrapper around a C++ random number generator object (for reproducibility). The class persists a C++ random number generator throughout an R session to ensure a given seed generates the same outputs (on the same OS). If no seed is provided, the C++ random number generator is initialized using std::random_device.
