Rounding and issuing change in multiple currencies

@Jesse

Like Ticket.PSum if there is something for remaining amount

Yah, I did some searching on the Forum and these are the only ones mentioned:

result = (Ticket.PSum + Ticket.PreSum - Ticket.Tax)

@emre

PSum is non discounted amount. PreSum is pre tax servicing amount

Handler must be: Calculation_<calculationTemplateName>
