	GeomState ()
	Default ctor leaves all hashes at their default value (~0xLL)
	GeomState (const fdk::Hash &init)
	Set all hashes to a specific value.
fdk::Hash	hash () const
	Return a single hash consisting of all non-default hashes appended together.

bool	isDefineGeometryDefault () const
bool	isModifyValuesDefault () const
bool	isEditStageDefault () const
bool	isDefault () const
	Are all hashes at the fdk::Hash default value? (this won't work if hashes set to a different initial value)
void	set (const fdk::Hash &h)
	Set all hashes to a specific value.
void	set (const GeomState &b)
	Copy all the hashes from b GeomState.
void	reset ()
	Reset all the hashes to the fdk::Hash default value (~0xLL)
void	append (const GeomState &b)
	Append each of b GeomState's hashes.
void	appendIfNotDefault (const GeomState &b)
	Append each of b GeomState's hashes if they're not at the default value (~0xLL)

If a's hashes are not default they initialize this GeomState's hashes, then b's hashes are appended, otherwise if a's hashes are default then b's hashes initialize this GeomState's hashes and a's are ignored.
