*
* This is a QT-based graphical sink the takes a complex stream and
* plots it. The default action is to plot the signal as a PSD (FFT),
* spectrogram (waterfall), time domain I&Q, and constellation (I
* vs. Q) plots. The plots may be turned off by setting the
* appropriate boolean value in the constructor to False.
