* Calculates the registration's final price, taking into account that they

* 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. Eg
* array(
* 12 => 4.3
* 23 => 8.0
* 'total' => 16.6,
* 'taxable' => array(
* 12 => 10,
* 23 => 4
* ).
* So to find which registrations have which final price, we need to find which line item
* is theirs, which can be done with
* `EEM_Line_Item::instance()->get_line_item_for_registration( $registration );`
