/*-- Borrow -----------------------------------------------------------
 * Derived from 'Transaction'
 * Contains specialized functionality for Borrow Transaction types.
 *
 *-- Assumptions ------------------------------------------------------
 * - Default Constructor
 *   -> will only be invoked by TransFactory
 * - createItem
 *   -> parameters were checked for validity before being passed to
 *      this function. Item is a valid Item object.
