 // I noticed that the same basic code was showing up in all of the methods:
 //      output.Text = _controller.AcceptCharacter('?')
 // Whenever I see duplicated code, I want to get rid of it -- it's more places where
 // errors can occur, more things I have to read over to find the "meat" of the code,
 // more stuff to modify and maintain if I want to make a change later.
 //
 // So, I wrote this "helper method" to encapsulate the redundant "boiler-plate" parts of
 // that code.  Now, each button-click handler just says
 //      handleInput('?')"
 // and it's really easy to visually verify that each method does the intended thing.
