`sim.dpp.modal.nystrom()`

uses the DPP-based design emulator of Pratola et al. (2018)
to draw a sample of the `n`

-run optimal design for a Gaussian process
regression model with stationary correlation function *r(x,x^\prime)*, where the
entries of `R`

are formed by evaluating *r(x,x^\prime)* over a grid of candidate
locations. This function uses a grid-based Nystrom approximation based on the passed matrix `X`

to avoid constructing a large correlation matrix if dimension `ngrid^p`

and its subsequent eigendecomposition.
