Merged selftestingmd and annotationmd into this repo
Fixed some annotation bugs, started work on an abandoned bundle demo
Changed annotation format

Annotations are now specified with a level three header. This allows unambiguous multiline annotations. We also have markdown rendering for these annotations
Modified folder structure so all important files are at the root
Added subtitle, notes, improved bundle annotations
Fixed some style issues:

1) annotations are now slightly transparent to make it easier to understand that they can overlay over the notes below
2) default text now instructs one to click on an annotation
Added some more annoations/cards, added youtube video
