*--------------------------------------------------------------------
|

*
|
||||
* Sub-Class - UPC-E
|
||||
*
|
||||
* You can provide a UPC-A code (without dash), the code will transform
|
||||
* it into a UPC-E format if it's possible.
|
||||
* UPC-E contains
|
||||
* - 1 system digits (not displayed but coded with parity)
|
||||
* - 6 digits
|
||||
* - 1 checksum digit (not displayed but coded with parity)
|
||||
*
|
||||
* The text returned is the UPC-E without the checksum.
|
||||
* The checksum is always displayed.
