Subclass implementation of binarization.

void ppforest2::binarize::Binarization::regroup	(	NodeContext &	ctx,
		stats::RNG &	rng ) const

Reduce a multiclass partition to binary and store in context.

Public NVI entry point: skips if ctx.aborted is set, otherwise delegates to the subclass-provided compute.
