abstract: Fit Hawkes and log-Gaussian Cox process models with extensions. Introduced
  in Hawkes (1971) <https://doi.org/10.2307/2334319> a Hawkes process is a self-exciting
  temporal point process where the occurrence of an event immediately increases the
  chance of another. We extend this to consider self-inhibiting process and a non-homogeneous
  background rate. A log-Gaussian Cox process is a Poisson point process where the
  log-intensity is given by a Gaussian random field. We extend this to a joint likelihood
  formulation fitting a marked log-Gaussian Cox model. In addition, the package offers
  functionality to fit self-exciting spatiotemporal point processes. Models are fitted
  via maximum likelihood using 'TMB' (Template Model Builder). Where included 1) random
  fields are assumed to be Gaussian and are integrated over using the Laplace approximation
  and 2) a stochastic partial differential equation model, introduced by Lindgren,
  Rue, and Lindström. (2011) <https://doi.org/10.1111/j.1467-9868.2011.00777.x>, is
  defined for the field(s).
