From Sergei:

Fix white spaces, add more comment to functions, add CVS tag lines and copyright.
It should now work  for array of objects and most stl classes.
I put limitation for array size. If array with fixed size exceed limit (default 20),
array will be converted to raw data, otherwise each element of array will be presented as
single column.
