/**
 * Implements decoding of the ITF format, or Interleaved Two of Five.
 *
 * This Reader will scan ITF barcodes of certain lengths only.
 * At the moment it reads length 6, 8, 10, 12, 14, 16, 18, 20, 24, and 44 as these have appeared "in the wild". Not all
 * lengths are scanned, especially shorter ones, to avoid false positives. This in turn is due to a lack of
 * required checksum function.
 *
 * The checksum is optional and is not applied by this Reader. The consumer of the decoded
 * value will have to apply a checksum if required.
 *
 * http://en.wikipedia.org/wiki/Interleaved_2_of_5 is a great reference for Interleaved 2 of 5 information.
