// .NAME vtkSparseArrayToTable - Converts a sparse array to a vtkTable.
//
// .SECTION Description
// Converts any sparse array to a vtkTable containing one row for each value
// stored in the array.  The table will contain one column of coordinates for each
// dimension in the source array, plus one column of array values.  A common use-case
// for vtkSparseArrayToTable would be converting a sparse array into a table
// suitable for use as an input to vtkTableToGraph.
//
// The coordinate columns in the output table will be named using the dimension labels
// from the source array,  The value column name can be explicitly set using
// SetValueColumn().
//
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
