Another version number bump. I did a little bit of backtracking. 'Data::Printer' and 'Data::Dumper::Simple' are now optional. They will be used if available, otherwise 'Data::Dumper' is used.
Also, '__LINE__' is no longer necessary. '__LINE__' was used as 'caller' never seemed to give the right line number. I believe I have solved that problem. The code checks for a '__LINE__' parameter, but doesn't use it. You may leave this parameter out entirely.
