d2l-labs-ou-filter

A Lit component that renders org unit structure tree. It supports load more and searching functionality.

Note: this is a "labs" component. While functional, these tasks are prerequisites to promotion to BrightspaceUI "official" status:

• Design organization buy-in
• Architectural sign-off
• Continuous integration
• Cross-browser testing
• Unit tests (if applicable)
• Accessibility tests
• Visual diff tests
• Localization with Serge (if applicable)
• Demo page
• README documentation
