4.0 punch list

• Rename the model document to Presentation API Data Model, as it has classes and processing rules, not just properties (e.g. in the header of the model/ and the intro of index)
• The first sentence of the intro is correct but not useful as it doesn't define anything about the model and its serialization. Suggest merge into the next paragraph.
• I don't think that "the IIIF Manifest" is the document format. The format is JSON-LD compacted with the presentation API context. In particular the Collection class uses the same "format" as the Manifest. Suggest deleting the mdash parenthetical.
• I'll make a new diagram with Container instead of Canvas
• The (eyes) are weird. Could they be a note callout, or just add to the preceding text that describes the class requirements?
• Foundations: Concept of annotation... using an Annotation ...
• (to be continued)
