formerly presentation components such as `navigation` and `footer` have been nested, and renamed to `container` inside their respective component subdirs
1. Put formatting-specific components into the `presentation` subdir of `components`
2. Put content-specific components into the `container` subdir of `components`
3. Put views that are sub-urls of the site into a subdir of `views` (i.e. `microworlds`, and eventually `conference`)
We are recruiting Scratchers for interviews on the Scratch Community
blocks feature; this is a part of my PhD disseration. This commit has
the PDF forms and the views that are needed for the recruitment.
