Docstrings for cutoff_menu and LCA_results_tabs

[marc-vdm]

Docstrings updated/made in accordance with PEP8 and PEP257 for cutoff_menu and LCA_results_tabs
as recently proposed in #346.
Some commits from other users [or my lack of understanding git :D] are now under my name and I don't know why though. Please let me know if you know a way to fix that, I`m not here to claim credit for work I didnt do.

I really like this! Thank you for adding clear explanations of what is shown by each different LCA result tab.

I think I see what you mean about the commits, it looks like you've continued working on the same branch that was merged in #345. I'm not sure if there is a clean way of fixing this.
What I usually do when I find myself with something like this is storing the changed code somewhere and undoing commits until I reach a place where a fast-forward merge can be done. Though that can be a lot of work.

Happy to have done the work, someone had to, and as I partly wrote that code, I thought I should.
Ive looked at the commit business again, I think it should all be fine now, my master fork should now be in line with this master, so long as I keep fetching/pulling properly from here I think we should be fine!

I'll be merging this sometime later today or tomorrow, this has given me ideas while I was planning to work on something else.
