Description: Fast computation of the deviance of the Cox proportional
    hazards model (Cox (1972) <doi:10.1111/j.2517-6161.1972.tb00899.x>), its
    gradient and the diagonal of its Hessian with respect to the linear
    predictor, the information and its derivative in a direction as
    matrix-free linear operators, and draws of the score (multinomial,
    Bernoulli, Fisher noncentral hypergeometric or wild), with the ties of
    Breslow (1974) <doi:10.2307/2529620> or Efron (1977)
    <doi:10.1080/01621459.1977.10480613>, start times (left truncation),
    strata and sample weights. The 'C++' code is header-only, shared with the
    'Python' package 'coxdev', and installed for packages that use it through
    'LinkingTo'.
