recreate (or ditch) featureComparison

[city41]

The featureComparison page has largely been abandoned. It's built with dojo and is not easy to update.

I think it should get recreated with React and a React grid component, or dropped altogether.

One other thing to consider is when people contribute implementations, they are often a little befuddled by featureComparison. Maybe it was just a bad idea that should go away?

@city41 i just discovered this page while updating the repo. I think it's a good thing to have but only if its easily updated.
