Implementation of a SetEditor demo plugin for the Traits UI demo program.
The four tabs of this demo show variations on the interface as follows:
- Unord I: Creates an alphabetized subset, has no "move all" options
- Unord II: Creates an alphabetized subset, has "move all" options
- Ord I: Creates a set whose order is specified by the user, no "move all"
- Ord II: Creates a set whose order is specifed by the user, has "move all"
Please refer to the `SetEditor API docs`_ for further information.
