[dwc-mixs] Darwin Core to MIxS Core mappings - first pass

Hi folks,

Great meeting to get things started today. I have finished adding mappings from Darwin Core to MIxS Core in the spreadsheet Raïssa shared ( https://docs.google.com/spreadsheets/d/1k6Xe1OREUVISLjw1XLrtLqWsE7QgvWf7lSIX...). There are a few subtleties to be aware of, but I think I have captured all of that in the comments. One term, geo_loc_name, currently has two rows to describe it because I added one rather than replace Raïssa's.

Hopefully this is a useful start. I did not add issues yet because I do not have sufficient rights to make labels, which I would like to do and add them to the issues as I make them. It would be great if I could be granted that right.

Let me know if there are any questions.

Cheers,

John
