Problem

Some of the pdfttp scripts are broken and need to be fixed and added to examples/.

Fix these scripts then add them and corresponding tests. Find the scripts here: https://github.com/Billingegroup/pdfttp_data
Additional srfit examples here: https://www.diffpy.org/diffpy.srfit/examples.html
