allow forcing processing of identical bundles
- student is supposed to upload one 4-page pdf.
- student uploads four 1-page pdfs.
- 3 of the files are identical, thus answers are missing.
I wish to communicate this to the student (rather than them assuming I messed up and lost their files). Or: I don't want to look at the files and just upload whatever they gave me... In either case, I cannot b/c "A bundle with matching md5sum is already in system with a different name. Stopping".
Its nice that Plom doesn't want me to shoot myself in the foot but in some workflows I want to take the shot. Probably some workflows we haven't thought about yet too.
Solution: add -f/--force
? Then it would warn but not die.
