Fixed bug in clone method
Stupid bugs because I'm stupid.
Gotta keep dem function names consistent.
Removed log statements
I think we should just let exceptions bubble up rather than be passed to
the errback. For now, at least.
Finished and fixed up the WL kernel implementation
Use WL kernel by default
Created a context menu for the compare visualization
Added a Tooltip implementation for the compare graph visualization
Offloaded some compare graph visualization styling into CSS
Keep the ID as a private variable with accessor function, so that it
cannot be modified.
Add tooltips and context menus to the visualization
