Tree hover should highlight the rows/cols on the matrix which correspond to the hovered subtree

[Robert Leach]

USE CASE: WHAT DO YOU WANT TO DO?

Make it easier to make disparate visual associations across the matrix from the trees.

STEPS TO REPRODUCE AN ISSUE (OR TRIGGER A NEW FEATURE)

1. Open a file which has a row tree
2. Hover over a subtree of the row tree pane (not a leaf)
3. Press and hold the shift key on the keyboard
4. Move the cursor to hover over a different subtree
5. Release the shift key

The same can be done for the column tree and control key.

CURRENT BEHAVIOR

As of pull request #99, only the hovered single row is highlighted.

EXPECTED BEHAVIOR

The highlight should encompass all rows involved in the hovered subtree.
