    Line 0) This is the root of the whole SVG canvas of the Topology View - all
        components beneath it are SVG components only (no HTML)
    line 1) the No Devices Connected banner is shown if the force component
        (from line 4) does not contain any devices
    line 2) Create an SVG Grouping and apply the onosZoomableOf directive to it,
        passing in the whole SVG canvas (#svgZoom)
    line 3) Add in the Background Svg Component (if showBackground is true - toggled
        by toolbar and by keyboard shortcut 'B'
    line 4) Add in the layer of the Force Svg Component. If any item is selected on it, pass
        to the details view and deselect all others. This is node and line graph
        whose contents are supplied through the Topology Service, and whose positions
        are driven by the d3.force engine
