GSoC 2023: Outliner Tree Refactoring

[shinbay]

Report Week 1 (May 29 - June 2)

This week’s progress:

• Two main branch commits:
  – f63c3075cb: Port mesh elements to new tree-element code design
  – 8374208a57: Port curve elements to new tree-element code design
• After the discussion with my mentor, I started working on default expand() of TreeElementID to avoid a bunch of small classes that only differ slightly
