save annotations separately based on region name and not just the entire slice about microdraw

[pglock]

Hi
What should a database entry for a region look like?

Currently:

• source: file identifier
• user: UserID, who made the annotation
• section: section identifier
• annotationHash: needed for undo
• annotation: the region path and the name
• backup: Flag, replaces timestamp?

I'd like to propose some new attributes:

• type: the type of the annotation, e.g. "cells", "cortigal_region" or "artifact"
• visibility: private/public, if public everyone can load the annotation

/api get request

At the moment source and section are queried. If source is the fileID, querying source and user should be sufficient. The request should return an array of all queried annotations.

/api post request

The post request should be able to save a list of annotations ( all annotations of the current section) to the database.

client changes

• provide type value
• provide visibility value, can default to private
• expect a list of annotations from get
• provide a list of annotations for post

Looking forward to your remarks ;)
