-/************************************************************
-      This example shows how to read and write data to a dataset
-      using the Scale-Offset filter.  The program first checks
-      if the Scale-Offset filter is available, then if it is it
-      writes integers to a dataset using Scale-Offset, then
-      closes the file Next, it reopens the file, reads back the
-      data, and outputs the type of filter and the maximum value
-      in the dataset to the screen.
