 Need to extend the unary anad binary operations performed on dataset 2d to
 IXTrunfile. Tentative scheme is:
 If runfile = (all other stuff) x (array of dataset2d)  x   i.e. r = a x d,
 then

 unary operations:  f(r) = a x f(d)

 binary operations: with scalar, vector, d1d, d2d:
                       f(r,v) = a x f(d,v) ; validity determined by
 validity of f(d,v)
                    between two dataset 2d:
                       f(r1,r2) = a1 x f(d1,d2) ; valid if f(d1,d2) valid.

 This means that if divide r1/r2, picks up the sample, chopper etc of r1:
 that is what we'd like if normalising by vanadium run. If wanted the
 result to pick up r2, then we'd have to do (1/r2)xr1.

 This scheme is subject to TGP checking against the consistency with
 scalar, vector, d1d and d2d operations.
