RE: PROV-ISSUE-2: proposal to vote on - process execution in the past

To clarify my "provenance is past tense" entry on the irc today - to me
the important thing is that provenance is an account in the past tense
of what has occurred, not what might occur. That simply means you'll
never have to describe both branches of a coin flip - after it has
happened (past tense), only one branch occurred. If you want to write
down in PIL that in the future a coin flip will have resulted in
'heads', I don't think it's an issue. If you want to talk about the two
potential outcomes, I think we'd need to add to the language and it
wouldn't be provenance anymore (workflow instead).
