#16 Browsing feature: hide nodes by name or order

[Richard C. Yeh]

Sometimes when browsing very dense graphs, it would be nice if I could remove nodes or edges that I don't care about, and have the software redraw the graph instantly.

I would like to be able to selectively exclude nodes (and associated edges) by name, class, order (inward edges, outward edges, or total).

This may conflict with bug [ 1904783 ]: if a central node is removed, the graph may become multiple disconnected components.
