Document available datasets

[Irio]

Preferably in the README itself. What data we currently have? How to find out more about each variable?

Comes to better answer questions like @rafaelalmeida's here: #39 (comment).

Complementary to this one, I'm working on @cuducos' pull request generating a Markdown document the main dataset we've been working these days, #25.

And yet anther complement, we might want to document what each script inside src/ does. @Irio have you raise this issue thinking of taking it over? I can try sending a PR on that until Monday.

@cuducos I'm generous enough to distribute issues with anyone who wants one. 😄

I’d suggest adding it to CONTRIBUTING.md instead of README.md. When we discuss the purpose of each directroy, I think we can add a sub-section explaining more about the datasets, and one subsction to explain the purpose of each script in src/.

Anyway, gonna send a PR soon and copy and paste makes it easy to move the contents around ; )

And I also believe it makes no sense to have Public Data Lists and Strategies for Mass Collection in READMEs anymore. All those ideas are recorded and discussed into Issues now.
