Retrieving abstracts from pubmed based on spread-sheet

[aubertc]

The goal is to

1. gather some information from a spreadsheet (how much is still open: only title, title + author, something else?)
2. retrieve the corresponding abstract from pubmed,
3. insert that abstract back into the spreadsheet.

My attempt at 2 is at https://github.com/popbr/data-integration/tree/main/Abstract_finder

A few notes:

• w3c and jsoup classes both define Elements and Document (among other), so I commented out the w3c class and the methods that were relying on it.
• The current workflow is to "ping" the server and retrieve the html file. There may be much better options using an API, but I haven't looked into it.
• There will need to be some error-catching implemented, as my program right now always assume that exactly one page containing exactly one abstract is returned.
