(Admin) Reorg repository

[iherman]

The current repo still has the ocf-lite document as a 'side' document, as if it was a secondary note. We should reorganize to reflect the reality. This may mean:

1. We set up a separate repository and we move this draft there. The current repository should be marked (eg, in the README) as, say, 'postponed', or something similar
2. We keep the current repository, in which case:
   • the current index.html file should be moved into some other subdirectory ('attic'), duly marked as postponed
   1. the current spec/ocf-lite.html should become the index.html file, ie, the main entry to the repository
   2. the README file should be updated
   3. because this document would not replace the current pwp document, it would have to have its own short name, should go through the FPWD publishing phase, which should also mean some admin to do v.a.v. ECHIDNA

These steps also depend on the outcome of issue #39
