/**
   The comments below are most likely not valied anymore since
   the rewrite of LyXFindReplace0 and LyXFindReplace1. (Lgb)
   
  LyXFindReplace0
 
  This is a virtual base class. It does not handle text specific
  items. It only manages the Find & Replace form and the variables.
  
  To be added:

  - Confirm replace lightbutton (checkbox)

  - A history list for search and replace strings.
  These 2 stringlists should match, so that you can replay previous replaces.
  If you select another search string, then the first choice should be the 
  replace string you have typed before.
  
  - regex searches (I'm working on that -- dnaber, 1999-02-24)
