Improve how Report relationships/links are handled

[gtback]

If a Bundle contains a Report which refers-to most other objects in the bundle (like the current apt1.json file), the graph view is hard to read, since most objects arrange themselves in a circle around the report at the center.

Possible suggestions:

• Don't create links for Report objects
• Make the links much lighter (in color) and lighter (in weighting for the force-directed graph). That would let you see all the report links but not obscure the more "important" relationships.

I'm sure other people have better ideas.

The same is probably true for created_by_ref links.

Another solution would be to have a toggle switch for each of these types of relationships, and (perhaps) disable by default when there are more than a fixed number of each type (5 or 10, maybe).

Also, the marking references should be toggle-able in the same way.

Just a status update
I've had to rework the repo to use D3js v4 to get access to the collide() function which allows a node to have a collision radius. Doing so allows greater node separation when looking at a lot of SDOs.

There are no more syntax errors but functionality is not the same as v3. Turns out a lot of functions change parameters, output, and may not even exist anymore. Backwards compatibility was extremely limited.

Once core functionality is restored a pull request will be made. Then a separate branch will be created for the collide capability.

Current status outlined in 098e174. Unfortunately, without taking the time to learn Javascript and D3js v4 from the ground up, there are still usability issues to iron out.
