Just for fun I've created a template for how the least common multiple
of our expectations could look like.  I guess there are many different
expectations of how contents, visualizations and ways of saving for
notes could look like, so I made it so that all of that is changeable
and extensible.

I'm not yet sure what would have to be done to support mass annotation
from occur buffers since I don't use them a lot.

I'm also not sure where in the implementation I could rely on existing
code - especially for saving (eieio-persistent maybe?).
