Create a generic example to demonstrate the use of easyVVUQ with similar functionality to the evaluate_uncertainties.py tool in PROCESS

[ym1906]

I wanted to note some of the tasks I should do to help us formalise the easyVVUQ work:

1. Establish a method for parsing PROCESS input and output w.r.t. easyVVUQ (account for failed runs where no MFILE is produced)
2. Create an example job script and evaluation notebook (demonstrate Monte Carlo sampling).
3. Convert the samples dataframe to hdf format, and save it.
