Add a ScreenOutputGenerator

The new generator prints the records on screen using the
System.out.println method.
Minor modification in ScreenOutputGenerator
Fix a bug in CSVDataLoader

A run time error would be thrown if the input mapping specified a column
number that did not exist in the input file. The data loader detects
this condition and throws a MalformedSourceException instead.
