Keynote content from James H's SSI report

Hi Dan,

I copied the content summarising the keynotes from my SSI conference report on SC13/WSSPE into the WSSPE summary paper.

If you think summaries of this class are useful, please accept the PR, and I can add the similar content from my notes about each of the other sessions...

Feel free to reject the PR if this isn't the style of content you're aiming for...
