The KeySet class is a regular type that represents a collection of Keys.
Users can construct a KeySet instance, then add Keys and ranges of Keys to the set. The caller is responsible for ensuring that all keys in a given KeySet instance contain the same number and types of values.
Users may also optionally construct an instance that represents all keys with KeySet::All().
