Add a geo lesson/section

[nuest]

... as preparation for https://geostat-course.org/2017

• [ ] small example of RMarkdown, with analysis using sf
• [ ] example with RQGIS
• [ ] small example with SWeave?
• [ ] example with QGIS based on a Python script
• [ ] geoservices in containers (is this relevant for RR?)
  • we could package a geoserver-based analysis, of course...

@thengl @barryrowlingson @jannes-m @becarioprecario Here is my material for this weeks EGU short course on "Docker for Reproducible Research", which I would like to extend with spatial stuff for this year's GEOSTAT. Any input as to potential content is highly appreciated!

What exactly do you have in mind? Should I just provide you with a simple RQGIS example? I'll gladly do that.
