nfold command does not print anything to screen or save to file.

I have been investigating this issue and it seems like the bug is in the listkernel at the set() command at the end of the listkernel function. From what I can see, this set() command should not be run without an object, right? The crash is related to the fact that the vector in value_list is size 0.

To help debug this, let me provide the output of the GDB command. I will stop here and wait for some feedback on this matter.

Nfold Command

nfold data/hexatic.dat 6 ./inputs/sigma_matrix xy 1.4 hexaticorder hex 0 0
