[kairi003]

📑 Summary

It improve its support for notes inside namespaces.

Resolves #4706

📏 Design Decisions

It allows NoteNode to be added in the namespace.

• classStatements parses not only classStatement but also noteStatement and returns an array of their IDs.
• addClassesToNamespace() takes a new param noteNames and associates the namespace with the note.
• In classRender-v2.ts addNotes() implements the process of adding to namespace like addClasses().
• Changed notes from Array to ClassNoteMap.
• Add fields to ClassNote.
  • parent: keeps the ID of the namespace.
  • index: holds the number of the note. index: holds the number of the note (used as a reference when generating the edge ID)
