Control and display widgets

The pothos-widgets package contains a family of blocks that have graphical widget representations. Widget-aware blocks can be tied into the topology like any other block, but also have a associated widget that can be displayed and manipulated within the Pothos GUI.

The signal-analysis family of plotters can be used to visualize streaming sample data, and discrete packets of sample data.
