   9 // This returns an associative array keyed on procedure code, representing
  10 // all charge items for one invoice.  This array's values are themselves
  11 // associative arrays having the following keys:
  12 //
  13 //  chg - the sum of line items, including adjustments, for the code
  14 //  bal - the unpaid balance
  15 //  adj - the (positive) sum of inverted adjustments
  16 //  ins - the id of the insurance company that was billed (obsolete)
  17 //  dtl - associative array of details, if requested
  18 //
  19 // Where details are requested, each dtl array is keyed on a string
  20 // beginning with a date in yyyy-mm-dd format, or blanks in the case
  21 // of the original charge items.  The value array is:
  22 //
  23 //  pmt - payment amount as a positive number, only for payments
  24 //  src - check number or other source, only for payments
  25 //  chg - invoice line item amount amount, only for charges or
  26 //        adjustments (adjustments may be zero)
  27 //  rsn - adjustment reason, only for adjustments
  28 //  plv - provided for "integrated A/R" only: 0=pt, 1=Ins1, etc.
  29 //  dsc - for tax charges, a description of the tax
  30 //  arseq - ar_activity.sequence_no when it applies.
