vcSelectFigure

 Open an ISET window and return a figure number 

   figNum = vcSelectFigure(objType,noNewWin)

 Purpose:
   If the ISET figure is already open, the existing figure number is returned.  If
   the ISET window is not opened, then the function that opens the window
   is called and the new figure number is returned.

   You can suppress opening a window  by setting noNewWin = 1. In that case, if
   no window exists figNum will be returned empty and no window will be opened.

 Example:
  figNum = vcSelectFigure('GRAPHWIN');
  figNum = vcSelectFigure('scene',1);
  figNum = vcSelectFigure('scene');
  figNum = vcSelectFigure('oi');
  figure(vcSelectFigure('ISA'));
