class NonEmptySet<T> : MutableSet<T>
A set which is constrained to ensure it can never be empty. An initial value must be provided at construction, and attempting to remove the last element will cause an IllegalStateException. The underlying set is exposed for Kryo to access, but should not be accessed directly.
