// Package sets implements set types.
//
// This is forked from k8s.io/apimachinery/pkg/util/sets (under the same project
// and license), because k8s.io/apimachinery is a relatively heavy dependency
// and we only need some trivial utilities. Avoiding importing k8s.io/apimachinery
// makes kind easier to embed in other projects for testing etc.
//
// The set implementation is relatively small and very stable.
