**      GetFindResults Macro
**      Purpose: Collect all current "Find (in Files)" results in Find Results tab 1
**                      into new (or reused) window for subsequent processing.
**      Author: Dave Wald
**      Date:   April, 2012
**      Notes:  Make sure there is a current Find Results window with lines of text in it,
**                      or it will just tell you it can't find anything to process.
**                      It only gets the "Find Results 1" pane now, but could easily be copied to do "Find Results 2" as well.
