// provides a GUI for monitoring workflows. Will do.  In theory.
//
// Let's think about what our ideal gui will look like:
// - displays a drop-down for selecting from available workflow names
// - button to add a new workflow
// - button for deleting a workflow
// - button to save all workflows, deleting any no longer in existence
// - button to restore all workflows from file
// - button to save current workflow
// - button to restore current workflow form file
//
// then, for each workflow:
// - display a line for each request
//   - the contents of the workflow file
//   - how many of these units exist in the game right now, as friendly units
//      - a button to press to show them on the map
//   - how many under construction at the moment
//      - a button to show them on the map
//      - maybe have their percent construction
//      - maybe put each of them on separate lines? with a progress bar for each
// - be able to add new lines, specifying priority, selecting unit from
//   current buildtable, by human name, shortname
// - be able to edit current lines, editing quantity, priority, and unit name (?)
//
// conundrum: how much to use reflection, and how much just to statically code?
