[barcode] Apologies

[David Humphreys]

I'm sorry for not replying to any of the email in time.   I was up to my 
eyeballs in college work for all of last week, so I hadn't checked my email in 
many days.
I will be off college next week for three weeks (for the last week, I will be 
on holiday)
I will clean up my bit of code.
The major areas that I will concentrate on are;
* Incorporate it into the library -- just add a few lines and flags
* Clean up the code
