CompareKeys returns sets of added and removed keys between two sets. Elements present in the set but not in the other are returned as 'added'. Elements present in the other set but not in set are returned as 'removed'. of false.

(other TimedSet)

// Elements present in the other set but not in set are returned as 'removed'.
// of false.
func (set TimedSet) CompareKeys(other TimedSet) ChangedKeys {

	changed := make(ChangedKeys)

	// Elements in set but not in other
	for ch := range set {
		if _, ok := other[ch]; !ok {
			changed[ch] = true
		}
	}

	// If no additions and lengths are the same, then set keys are identical
	if len(changed) == 0 && len(other) == len(set) {
		return changed
	}

	// Elements in other but not in set
	for ch := range other {
		if _, ok := set[ch]; !ok {
			changed[ch] = false
		}
	}
	return changed

}

// TimedSet can unmarshal from either:
//  1. The regular format {"channel":vbSequence, ...}
