Set width of tree based on tree data

[seachel]

Parent Issue

If the d3 tree width can be updated, then pass the new width once the tree has been fully formatted and laid out.

Have a running sum of the width.

Otherwise, consider creating the tree with node size rather than tree size.

First solution:

Have width as field for each tree. The width will need to be found through trial and error for each example.

[seachel]

Later solution:

Find width of largest node and compute width of tree. Add in spaces, multiply by width of widest node.
