Description: Creates spatially or environmentally separated, or
    group-preserving, training and testing folds for k-fold,
    leave-group-out, and leave-one-out cross-validation. Provides spatial
    blocking, clustering, buffering, and nearest-neighbour distance-matching
    methods, together with tools to visualise folds, summarise fold sizes and class balance, 
    and assess train–test separation and environmental novelty. Also estimates spatial
    autocorrelation ranges in point samples and continuous raster covariates
    to provide an initial distance scale for designing spatial folds. Methods
    are described in Valavi, R. et al. (2019)
