QT GUI Vector and Matrix Sinks
The two sinks that plot a whole vector at a time rather than a stream. Stream to Vector cuts the noisy tone into 256-sample frames; the Vector Sink draws one frame as a trace against its sample index, and the Matrix Sink draws the same 256 numbers as a 16x16 intensity grid, filled a row at a time.
