     //      will not work as expected.  Therefore, I've

     // UPDATE:  Actually, we do want variables set here so that they
     // are available in Custom Initialize.
     // UPDATE2:  This was moved to its own method so that inheritance works.
     // UPDATE3:  It turns out there's 2 types of variables.  
     // 1.   Variables that are not set by derived.  These variables should get set
     //      in the base class or else they'll never get set for derived objects.
     // 2.   Variables that are set by derived.  These variables should get set in the
     //      "SetCustomVariables" method so that they get overridden by derived objects.
     // This means that we're going to set variables that are not set by derived here, and the
     // rest will get set in SetCustomVariables.
     // UPDATE4:  This has all moved to PostInitialize, which is called
     //           bottom-up.  This means there is no more split on variables.
     // UPDATE5:  This has been moved out of BaseElementTreeNode int CustomVariableCodeGenerator.
