Problem: it is unclear how to navigate in DativeRF

[jrwdunham]

A/C:

• Add a menu and navigation scaffolding
• In the original Dative, this is a desktop-like top-level menubar, with sub-menus. We may want to repeat this pattern since it is familiar to current users and seems effective.
  • The fact that many "resources" are under a "Resources" menu item, however, is not readily understandable for many users, so we may wish to change this.
  • A different style of menu may be chosen if it is significantly easier to implement
• Ensure future developers can easily add new items to the menu for their new features.
