B.2.1.23 Overset Holes

holewrite	Create a new overset hole node
	`hole-id:I=`holewrite`(base-id:I,zone-id:I,hole-name:S,g-location:S,point-array:A)`
	$\rightarrow$ The grid location is a string. The corresponding enumerate can befound using the cross dictionnary.
holeinfo	Get info from a given overset hole node
	`return-tuple=`holeinfo`(base-id:I,zone-id:I,hole-id:I)`
	$\rightarrow$ Returns a tuple containing 'name:S' of the overset hole,'grid-location:I' of the returned set(s) of points,the 'point-set-type:I', the 'number-of-point-sets:I' and the/number-of-points-per-point-set:I'.Should be called before holeread* in order to have array dimensionsbefore allocation.*
nholes	Get the count of overset holes
	`number-of-holes:I=`nholes`(base-id:I,zone-id:I)`
	$\rightarrow$ Returns the number of overset holes in the current zone
holeread	Get info from a given overset hole node
	`point-array:A'=`holeread`(base-id:I,zone-id:I,hole-id:I)`
	$\rightarrow$ Gets the array containing the points. Dimensions depenson the PointSetType (see holeinfo).
