More YAML hacks

There are many more customizations for RMarkdown reports, and most of them can be configured via the YAML header.

Instructions

Hide all the code chunks by default by specifying the appropriate key-value-pair in the YAML header.
- Use code_folding for this, together with either hide or show, whatever makes sense here.
Try out another setting: Add numbers to all sections with the number_sections option.
Remember: All these settings hierarchically belong to the html_document key.
