Label:	`DataArray_t`
Data-Type:	`R4` or `R8`
Dimensions:	2
Dimension Values:	`CellDimension`, `PointListSize[]`
Data:	Interpolants for each node
Cardinality:	0,1
Parameters:	`CellDimension`, `PointListSize[]`

See:	`CGNSBase_t` figure

Notes:

The nodes PointRange and PointList are mutually exclusive.
For mismatched interfaces, the combination of CellListDonor and InterpolantsDonor is used to define the position of each receiver point in the donor zone.
cgsize_t is determined by the application from which the node is written. For a 32-bit application, cgsize_t will be I4, and I8 for a 64-bit application.
