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.
