    /*
     * A QR Code symbol, which is a type of two-dimension barcode.
     * Invented by Denso Wave and described in the ISO/IEC 18004 standard.
     * Instances of this class represent an immutable square grid of dark and light cells.
     * The class provides static factory functions to create a QR Code from text or binary data.
     * The class covers the QR Code Model 2 specification, supporting all versions (sizes)
     * from 1 to 40, all 4 error correction levels, and 4 character encoding modes.
     *
     * Ways to create a QR Code object:
     * - High level: Take the payload data and call QrCode.encodeText() or QrCode.encodeBinary().
     * - Mid level: Custom-make the list of segments and call QrCode.encodeSegments().
     * - Low level: Custom-make the array of data codeword bytes (including
     *   segment headers and final padding, excluding error correction codewords),
     *   supply the appropriate version number, and call the QrCode() constructor.
     * (Note that all ways require supplying the desired error correction level.)
