Detailed Description

[UI] Device overlay container

This class implements the (base) overlay corresponding to device overlay. The device overlay is not exactly an overlay since it is not meant to be drawn on top of the displayed chart. On the other hand, having devices available for inspection/configuration in the tree view (dock widget) is quite handy.
