anvl: Accelerated Array Computing and Automatic Differentiation

Accelerated array computing and code transformations for R. Numerical programs operating on multi-dimensional arrays can be just-in-time compiled to optimized executables via 'XLA' -- the same compiler that powers 'JAX' and 'TensorFlow' -- and run on CPU or NVIDIA GPU from the same source. Also provides reverse-mode automatic differentiation, returning the gradient of a function as another R function.
