--------------------------------------------------------------------------------

This is a pre alpha release /!\

One can generate the following codes: 1-M, 1-H, 2-L, 3-L 
Alphanumeric and binary encoding are supported. Note, that alphanumeric mode is 
NOT casesensitive.

EXAMPLES
========
To save a qr code to file.
>>> import qrcode
>>> qrc = qrcode.QRCode() 
>>> qrc.encode("HTTP://QR-CODE.CO.ZA") 
>>> img = qrc.to_image()
>>> img.save('./code.png')

To display a qr code as text. 
>>> import qrcode
>>> qrc = qrcode.QRCode() 
>>> qrc.encode("HTTP://QR-CODE.CO.ZA")
>>> s = qrc.to_string(on='g') # g rendered as black box when font set to Webdings
>>> print(s)

TODO
====
* update testcases
* clean up, refactor rewrite
  * validate input lengths
  * encapsule the various specification tables
  * look into the bitlist helper
  * use appends instead of concats with lists
* make code more robust or at least crash rather than producing garbage
* optimal mask selection (currently 011 is used)
* add support for version > 3
* automatically select version that best fits data if none specified
* add support for microqr

LIMITATIONS
===========
Too many to list

KNOWN ISSUES
============
Generating a 1-M for too long input results in a code that crashes the Android barcode
scanner. Probably due to some incorrect padding (0000 and 236,17) on my side.
