This will generate a function signature in the source code with the const qualifier for the selected parameter, once the transformation is executed.
这样，当转换执行的时候，将在源代码中为选定的参数生成带有常量修饰符的函数签名。

The chain code was replaced by the shape signature and used to express the contour, improve the speed and decrease the effect of noise and transformation due to camera calibration.
The way of loading message is that Alice does transformation operation on the first qubit unitary respectively, and the Bell measurement results of quantum bits are the signature of a message.
