+	 * Calculates the registration's final price, taking into account that they
+	 * need to not only help pay for their OWN ticket, but also any transaction-wide surcharges and taxes,
+	 * and receive a portion of any transaction-wide discounts.
+	 * eg1, if I buy a $1 ticket and brent buys a $9 ticket, and we receive a $5 discount
+	 * then I'll get 1/10 of that $5 discount, which is $0.50, and brent will get
+	 * 9/10ths of that $5 discount, which is $4.50. So my final price should be $0.50
+	 * and brent's final price should be $5.50.
+	 * In order to do this, we basically need to traverse the line item tree calculating
+	 * the running totals (just as if we were recalculating the total), but when we identify
+	 * regular line items, we need to keep track of their share of the grand total.
+	 * Also, we need to keep track of the TAXABLE total for each ticket purchase, so
+	 * we can know how to apply taxes to it. (Note: "taxable total" does not equal the "pretax total"
+	 * when there are non-taxable items; otherwise they would be the same)
+	 *
+	 * @param EE_Line_Item $line_item
+	 * @param array        $billable_ticket_quantities  array of EE_Ticket IDs and their corresponding quantity that
+	 *                                                  can be included in price calculations at this moment
+	 * @return array        keys are line items for tickets IDs and values are their share of the running total,
+	 *                                                  plus the key 'total', and 'taxable' which also has keys of all
+	 *                                                  the ticket IDs.
