// This returns an associative array keyed on procedure code, representing
// all charge items for one invoice.  This array's values are themselves
// associative arrays having the following keys:
//
//  chg - the sum of line items, including adjustments, for the code
//  bal - the unpaid balance
//  adj - the (positive) sum of inverted adjustments
//  ins - the id of the insurance company that was billed (obsolete)
//  dtl - associative array of details, if requested
//
// Where details are requested, each dtl array is keyed on a string
// beginning with a date in yyyy-mm-dd format, or blanks in the case
// of the original charge items.  The value array is:
//
//  pmt - payment amount as a positive number, only for payments
//  src - check number or other source, only for payments
//  chg - invoice line item amount amount, only for charges or
//        adjustments (adjustments may be zero)
//  rsn - adjustment reason, only for adjustments
//  plv - provided for "integrated A/R" only: 0=pt, 1=Ins1, etc.
//  dsc - for tax charges, a description of the tax
//  arseq - ar_activity.sequence_no when it applies.
