-	 * Class to create QR-code arrays for TCPDF class.
-	 * 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.
-	 * Currently the following features are not supported: ECI and FNC1 mode, Micro QR Code, QR Code model 1, Structured mode.
-	 *
