Item access to classes

[jesper-friis]

Description

Added item access, assignment and deletion to classes.

For now only annotation properties are supported. Rationale:

• only annotations are directly related to a class - all other properties are restrictions
• is_a, equivalent_to, disjoint_unions, disjoints, ... could be supported. But how do do the selection? And what is the added value compared to access these as attributes or methods directly?

Type of change

• Bug fix.
• New feature.
• Documentation update.
• Test update.

Checklist

This checklist can be used as a help for the reviewer.

• Is the code easy to read and understand?
• Are comments for humans to read, not computers to disregard?
• Does a new feature has an accompanying new test (in the CI or unit testing schemes)?
• Has the documentation been updated as necessary?
• Does this close the issue?
• Is the change limited to the issue?
• Are errors handled for all outcomes?
• Does the new feature provide new restrictions on dependencies, and if so is this documented?
