Public Member Functions
	KeyOnly (const Key &k_)
	KeyOnly (Key &&k_)
template<class... T>
	KeyOnly (T &&... args)
const Key &	key () const
	access key value – only const access is possible, key should not change
ValueType &	keyvalue () const
	universal access to key / key-value pair
void	swap (KeyOnly &k_)

Static Public Member Functions
static const Key &	key (const ValueType &k)
	helper to extract the key from ValueType – contrast it with KeyValue

Static Public Attributes
static const bool	keyonly = true

Protected Attributes
Key	k
	actual key; should not change during a node's lifetime – not const to allow swapping / moving nodes
