Show visible/hidden nodes count

[ungentilgarcon]

it would be great to have a debug mode window showing:
the amount of nodes visible on graph (in realtime so that each change or find affects it)
the amount of nodes visible on graph in realtime

The main filtering of nodes and edges is happening on client-side here.

topogram/imports/client/ui/pages/TopogramViewComponent.jsx

Lines 291 to 294 in f0515b1

	const edges = this.props.edges
	.filter(e =>
	nodeIds.includes(e.data.source) && nodeIds.includes(e.data.target)
	)

The best idea will be to get the length of the array as a totalNodesCount and totalEdgesCount and pass it down to the < SidePanel /> component so it can be shown in the description panel

topogram/imports/client/ui/components/SidePanel/SidePanel.jsx

Lines 98 to 102 in 345e73b

	<PanelDescription
	topogram={topogram}
	nodesCount={nodes.length}
	edgesCount={edges.length}
	/>

The best will be to show sth like 10 (on 12) nodes, 13 (on 15) edges in the UI of <PanelDescription />

topogram/imports/client/ui/components/SidePanel/PanelDescription.jsx

Line 14 in 345e73b

subtitle={`${nodesCount} nodes, ${edgesCount} edges`}
