Data carpentry and other lessons sources

[marcosvital]

Hi, everyone! So, some of you suggested Data Carpentry lessons as a fantastic source of R lessons with the same purpose of this project. And I also got some emails with similar suggestions from other promising sources (from personal websites to university resources).

So I was thinking: maybe it will be a good ideia to compile some of those sources inside our project, so anyone browsing our project can be directed to those other sites to get more material. What do you think?

We could start by compiling a list here, and organizing it inside the repository later. Let me hear what you all think about that.
