Create a ColumnSlicer for use in one of the overloads of ArrayColumn::getColumnCells.

That method takes a potentially complex select of data out of a column cell (e.g., multiple slices along each axis) and then puts them into a selection of a destination array. This is most easily represnted as a set of source,destination slicers where one is applied to the cell and the other to the destination array.

The shape paramter is the shape of the destination excluding the row axis.

The Slicer objects provided (by pointer) will be owned by the ColumnSlicer object which will delete them in its destructor.

void casacore::ColumnSlicer::freeSlicers ( )

inlineprivate

The two Vectors contain pointers to objects so they need to be freed. They should have the same length normally, but during validation it's possible that they have different lengths.
