DataGeom
A parameter supplies the index of the column in the tuple
at which the positional coordinate(s) can be found.
Each position is represented by DataGeom.getPosCoords()
columns of
the tuple.
By convention positions are at the start of the tuple,
so if there is one position in the tuple it will be at icol=0,
and there are multiple positions the N'th one will be at
icol=N*getPosCoords().
An array of (at least) DataGeom.getDataDimCount()
elements is
supplied, and on success the data space coordinate values of the
row of interest is written into it.
