Working Example?

This looks fantastic but I cannot seem to locate all the files of the correct versions to make it work. Do you have a working example or zip of one that has all the files needed?

I've uploaded fixed gantt_sample2.php file, so to get working example, you need to download current version of TCPDF PHP classes, unpack zip into folder "tcpdf" in one of folders from your PHP "include_path" variable, or in the "current" folder, where gannt php examples resides.

Since that moment "require_once('tcpdf/tcpdf.php') won't raise exceptions or errors, and pdf_gantt will work as expected.
If somehow it won't work, please send me your email address, i'll prepare zip with a full working set and send you directly.
