gSeg: Graph-Based Change-Point Detection (g-Segmentation)

Uses similarity graphs to estimate change-points and their p-values. The default data-level interface constructs a k-MST with k=floor(sqrt(N)) and reports the max-type scan. The generalized, original, and weighted scans remain available explicitly.
