Plotting outputs with linfa.plot_res

[robmoss]

After running some examples (#13) I also have a few questions and comments about plotting the results:

• The linfa.plot_res module is mentioned in README.md, but not anywhere in the online documentation (unless I've missed it). I think it's plausible that a user might look at the online documentation, but not the GitHub repository, so perhaps this module could be included in the online documentation?

• I discovered that the folder name must end with a trailing slash, otherwise it raises an error:

  python -m linfa.plot_res -n trivial -i 25000 -f results
  Log file not found: resultstrivial/log.txt

  Line 162 of plot_res.py concatenates the folder and experiment names. Please consider using os.path.join() or pathlib.Path to construct file names.

Thank you for the comments!

• I have added the "plot_res" module to the online documentation under "post-processing and plotting".
• The "plot_res.py" file was edited to use os.path.join().
