<dd>&lt;p&gt;Encapsulates data masks for the data bits in a QR code, per ISO 18004:2006 6.8. Implementations
of this class can un-mask a raw BitMatrix. For simplicity, they will unmask the entire BitMatrix,
including areas used for finder patterns, timing patterns, etc. These areas should be unused
after the point they are unmasked anyway.&lt;/p&gt;</dd>
