         * <li>closeQuietly - these methods close a stream ignoring nulls and                               exceptions
         * <li>toXxx/read - these methods read data from a stream
         * <li>write - these methods write data to a stream

         * This class captures that difference, providing an enumeration to
         * control how filename comparisons should be performed. It also                 provides
         * methods that use the enumeration to perform comparisons.
