Provide a distinction between total real charges and those that that include adjustments

[Kathy Lussier]

I believe the new Billing Statement that will be available in 3.1 will go a long way towards clearing up confusion over what has happened with a billing transactions, particularly those that include waived overdue fines, lost billing that are then reversed when the item is returned, etc.

However, one piece of data that I think would further improve this interface is if we included a tally of what I call total real charges.

Right now, the total charges tally includes, for example, the original fines that accrued, the lost fee that applied, the fines that were restored when the lost item was returned, etc. In the end, the total charges can end up being a lot more than the patron ultimately paid.

The breakdown of total payments, total adjustments, and total voids is a big step towards clearing up how much of this bill was addressed through an actual payment. However, if the patron has not yet paid the entire bill, staff still have to use math to figure out how much of the 'total charge' reflects the amount of money that is ultimately assessed. The total real charge, which is essentially the total charge - (adjustments + voids), would allow staff to get this information at a glance.
