__Main class to create QR-code__.
|

QR Code symbol is a 2D barcode that can be scanned by handy terminals such as a mobile phone with CCD.
|
||||
The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness.
|

This class supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004.
|
