organization: postprocessing for HelicalBuckling

This commit adds a new script for post-processing functions used by HelicalBuckling test cases. Computation of norms and errors as well as plotting envelope are now done with the functions inside `helicalbuckling_postprocessing.py`. Also `.gitignore` is modified to discard `*.png` and `*.dat` files.
