Update website design

[bencomp]

The web presentation of results is in need of some design to make it more accessible and nicer to look at.

@kamurch, you have said you would take a stab at it, but today @alexbrandsen offered to make a start. Is that okay with you?

[kamurch]

@bencomp That's really kind--yes, that would be fantastic.

Ok, I'll get started on it when I get some time!
