Detailed Description

The PlotStatusLabel class shows status string as reported by DescriptedPlot in a frame.

Can work with more than one DescriptedPlot. Provides automatic adjustment of font size, depending on available space in parent layout. Also doesn't trigger layout resize, being happy with place it has.
