Storage accounting project page

I've created a project page for the storage accounting system. This will
allow Dave Kant and myself to better keep track of the open issues.

Could all sites continue to check the published numbers and report any
inconsistencies to me.

As usual, the storage accounting page can be found here:

Suggestions for improvements are welcome.
