%description
Fast scalable Gaussian process approximations, particularly well suited to
spatial (aerial, remote-sensed) and environmental data, described in more
detail in Katzfuss and Guinness (2017) <arXiv:1708.06302>. Package also
contains a fast implementation of the incomplete Cholesky decomposition
(IC0), based on Schaefer et al. (2019) <arXiv:1706.02205> and MaxMin
ordering proposed in Guinness (2018) <arXiv:1609.05372>.
