[ACME-SE] last remaining repo items

Hello repo team, I'd like to try to set up a candidate repository by this Friday. There are a couple items that are preventing me from doing so: 1. A confirmation from someone (Doug, Mark?) that the codes we've put on github match the versions that we want for v0. 2. A decision on what we want our history to look like. The choices are what you see in ACME-Climate/single-repo-example (full history) vs. ACME-Climate/CESM_Version (just version snapshots). Thanks, -Jim
