Description: Implements the Beta Kernel Process (BKP) for nonparametric modeling of
 covariate-dependent binomial probabilities, and the Dirichlet Kernel Process (DKP) for
 categorical or multinomial response data. Scalable global-local approximations
 are provided through TwinBKP and TwinDKP, using twinning-selected global subsets
 and local nearest-neighbour updates.
 Functions are included for model fitting, predictive inference with
 uncertainty quantification, posterior simulation,
 and visualization in one- and two-dimensional input spaces.
 Gaussian, Matern 5/2, Matern 3/2, and Wendland kernels are supported,
 with hyperparameters selected by multi-start derivative-free optimization.
