Ids::Id32	Alloc ()
	Allocate an object.

void	Dealloc (Ids::Id32 index)
	Deallocate an object. Just places it in freeids array for recycling.

	get single item from resource

const tuple_array_t< MEMBER, TYPES... > &	Get (const uint32_t index) const
	same as 32 bit get, but const

const tuple_array_t< MEMBER, TYPES... > &	ConstGet (const uint32_t index) const
	Get const explicitly.

void	Set (const uint32_t index, const tuple_array_t< MEMBER, TYPES... > &type)
	set single item

void	Set (const uint32_t index, TYPES...)
	set for each in tuple

const Util::Array< tuple_array_t< MEMBER, TYPES... > > &	GetArray () const
	get array const reference

Util::Array< tuple_array_t< MEMBER, TYPES... > > &	GetArray ()
	get array

const uint32_t	Size () const
	get number of used indices

void	Reserve (uint32_t size)
	grow capacity of arrays to size

void	Clear ()
	clear entire allocator and start from scratch.

void	UpdateSize ()
	Any reserve and direct array access might mess with the size.

void	TryAcquire (const uint32_t index)
	Spinlock to acquire.

bool	Acquire (const uint32_t index)
	Acquire element, asserts if false and returns true if this call acquired.

void	Release (const uint32_t index)
	Release an object, the next thread that acquires may use this instance as it fits.
