void	replaceCellId (int id, bool keepActiveFlag)
	Updates the cell id. For those who really know what they are doing. This function is a very specific function that should not be called lightly. It exists on behalf of the state dumping code and for helping other mesh implementations wishing to encode extra information on the cell id, like the XFem plugin that uses it to mark a cell as enriched or not.
int	offset () const
	Returns the offset in the global mesh cell nodes vector for this cell. Not part of the GmCell API and should NOT be marked as virtual.
void	setOffset (int offset)
	Updates the cell offset. Not part of the GmCell API and should NOT be marked as virtual.

Protected Attributes
GmPODVector< int, uint32_t, GmPODVectorFastGrow< uint32_t > >	_ghostList
	List storing cell ghost nodes. Uses a GmPODVector with size control based on a 32 bits value giving a 16 byte structure. (QVarLengthArray also does that but has the fixed part overhead and no overflow check).
Protected Attributes inherited from GmpCell< Base, Proxy, CellMeshData, T, N >
int	_cellId
	The cell index inside the mesh. MSB is used to control if the cell is active or not.
int	_nodeOffset
	Index in the mesh data for the first node for this cell.

protected

List storing cell ghost nodes. Uses a GmPODVector with size control based on a 32 bits value giving a 16 byte structure. (QVarLengthArray also does that but has the fixed part overhead and no overflow check).

IMPORTANT1: Using a 16 bytes control with PODVector does not reduce the structure size to 12 bytes due to the required alignment. IMPORTANT2: We use the fast growing algorithm since the number of ghost nodes per cell tend to be really small. IMPORTANT3: If changing the definition below in ANY way, you will also NEED to change the code in GmpCellMeshData::cellMemory(). The two are HIGHLY coupled.
