// Purpose is to hide rate rows from scheme or vacancy which are over-ridden at the relevant vacancy or placement level. If non-null value returned the rate will be hidden.
// New method introduced MHS 25/3/13 is less aggressive - it only hides rates which are totally occluded, date-wise, by the over-riding rate.
// Previous method commented out.
