AND-100: Add annotations (blocking calls).

Could we extract the formatting of the Point to a method?

We could have a different method for formatting / parsing objects that are part of other objects, not only for readability but also for avoiding replication.

In this case it may not be so important, as I think Points appear only in Annotations, but for example we are parsing Person in different points of the code. This made that when we fixed the "first-name parsing bug" in Person for Author, the bug in remained unfixed in Person for Editor.
