/*
* This is the logic of computing the total for an Entry, so you know
* what values to put into various Splits or to display in the ledger.
* In other words, we combine the quantity, unit-price, discount and
* taxes together, depending on various flags.
*
* There are four potental ways to combine these numbers:
* Discount: Pre-Tax Post-Tax
* Tax : Included Not-Included
*
* The process is relatively simple:
*
* 1) compute the agregate price (price*qty)
* 2) if taxincluded, then back-compute the agregate pre-tax price
* 3) apply discount and taxes in the appropriate order
* 4) return the requested results.
*
* step 2 can be done with agregate taxes; no need to compute them all
* unless the caller asked for the tax_value.
*
* Note that the returned "value" is such that value + tax == "total
* to pay," which means in the case of tax-included that the returned
* "value" may be less than the agregate price, even without a
* discount. If you want to display the tax-included value, you need
* to add the value and taxes together. In other words, the value is
* the amount the merchant gets; the taxes are the amount the gov't
* gets, and the customer pays the sum or value + taxes.
*
* The SCU is the denominator to convert the value.
*
* The discount return value is just for entertainment -- you may want
* to let a consumer know how much they saved.
