Nemo website updated

[Bill Hart]

Hi all,

I updated the Nemo website [1], including the contributors list and
references to Nemo in the literature.

Please take a look and see if there is anything

* wrong
* not giving you (enough) credit where it is due
* obviously missing

I don't want to spend too much time adding new material there. There's
infinitely more content that could be added. I'm mainly interested if
there is something I can fix that is seriously missing or wrong.

Bill.
