Detailed Description

Establish communication between QCPGraph and GraphItem.

Provides update on QCPGraph (data points, line style, color, etc) when GraphItem is changed. QCPGraph is added to QCustomPlot plottables, when controller is created, and removed from plottables when controller is destroyed.

For necessary manipulations on unsubscription.

Sets callback to be notified when row is about to be removed.

Callback will be called with (compound_item, tagrow). For MultiLayer containing the T_LAYERS tag, the signal will be triggered on layer deletion with (multilayer*, {T_LAYER, row}) as callback parameters.
