%description
Interface to 'libKriging' 'C++' library <https://github.com/libKriging>
that should provide most standard Kriging / Gaussian process regression
features (like in 'DiceKriging', 'kergp' or 'RobustGaSP' packages).
'libKriging' relies on Armadillo linear algebra library (Apache 2 license)
by Conrad Sanderson, 'lbfgsb_cpp' is a 'C++' port around 'lbfgsb' library
(BSD-3 license) by Ciyou Zhu, Richard Byrd, Jorge Nocedal and Jose Luis
Morales used for hyperparameters optimization.
