> Currently if the users does not give the combiner any columns to work against, it will
work against all columns.  This is dangerous, if a user accidentally forgets to specify columns
then their data could be unintentionally corrupted.  Something different needs to be done.
 
> Also classes that extend combiner should call super.validateOptions().
