Documentation mega index

[David Blevins]

I created a very high level view of our documentation as it exists  
across the various versions.  Hopefully a very macro few of things may  
help us "clear the fog" on documentation related thinking.  At least I  
found it very difficult to see the whole elephant.

The code I used to generate the page is attached to the page.  It's  
pretty small.  Should be a fairly easy manual process to regenerate  
the page once in a while if we find it useful.
