Implements specialized K-Nearest Neighbor (KNN) logic to
address the unique challenges of spatial modeling in archipelagic
environments. Standard contiguity models often leave significant
portions of island nations (e.g., 20% of the Philippines)
mathematically isolated. This package provides tools to ensure
100% network connectivity, neutralizing spatial bias and
enabling robust econometric inference. Methodology follows
