%description
Computes pseudo-realizations from the posterior distribution of a Gaussian
Process (GP) with the method described in Azzimonti et al. (2016)
<doi:10.1137/141000749>. The realizations are obtained from simulations of
the field at few well chosen points that minimize the expected distance in
measure between the true excursion set of the field and the approximate
one. Also implements a R interface for (the main function of) Distance
Transform of sampled Functions
(<https://cs.brown.edu/people/pfelzens/dt/index.html>).
