docs: Gets the valueCostPerUnit value for this LineItemSummary.
  
  @return valueCostPerUnit   * An amount to help the adserver rank inventory. {@link
  LineItem#valueCostPerUnit} artificially raises the
  value of
  inventory over the {@link LineItem#costPerUnit} but
  avoids raising
  the actual {@link LineItem#costPerUnit}. This attribute
  is optional
  and defaults to a {@link Money} object in the local
  currency with {@link Money#microAmount} 0.
