Description:


a primitive (non graphical) inspector for use on systems without
graphics or when the real inspector dies (i.e. the UI is locked).
Sometimes useful as a last chance to fix a broken UI / event handling.
Needs a console.

    MiniInspector openOn: Display

Attention:
    all printing is done via lowLevel _errorPrint messages,
    to ensure that output is to stderr, even if a logger is present, 
    or Stderr has been set to some other stream (Transcript).
    Also to avoid the logger's interfering and adding imestamp information.
