Closes #1 - Create initial website

Pull request for #1 
bq. I left things like this out on purpose because it's not a feature, it's one of the fundamental purposes of the Percolator.

I was thinking the same thing when I thought about adding this.   But the following thoughts swayed me : 

 * This is the 1st release
 * This document may be the 1st thing that someone who knows nothing about Fluo looks at.  They will have no idea what we have and have not done.
 * We have not implemented everything in the paper yet. Therefore I think we should either communicate what we did implement or what we did not implement.

In addition to communicating things not in the paper, I think we need to communicate what parts of the paper have been done and the maturity level.  Maybe the information should be organized in another way.
