Description: Write statistical models in R and fit them by MCMC and
        optimisation on 'CPUs' and 'GPUs', using Google 'TensorFlow'.
        'greta' lets you write your own model like in BUGS, JAGS and
        Stan, except that you write models right in R, it scales well
        to massive datasets, and it’s easy to extend and build on.  See
        the website for more information, including tutorials,
        examples, package documentation, and the 'greta' forum.
