Description: Exact automatic differentiation for R functions. Provides a
    composable derivative operator D that computes gradients, Hessians,
    Jacobians, and arbitrary-order derivative tensors at machine precision.
    D(D(f)) gives Hessians, D(D(D(f))) gives third-order tensors for
    skewness of maximum likelihood estimators, and so on to any order. Works through any R code
    including loops, branches, and control flow.
