Minimal API for object collections and objects
All kinds of objects may be displayed with the RRackTool if they implement a minimal protocol
For an object holding a collection of other objects and thus acting as a RFolder object:
- isRackFolder
- isEmpty
- notEmpty
For an object to play the role of an REntry object:
- item (may return the object itself)
- label (a string)
