/**
  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)
