Get GitHub Collaboration up

[kousu]

At an in-person meeting with everyone, we need to

1. make sure everyone is comfortable with pushing and pulling to this repo: everyone must make one change (this can be merged with 3.1)
2. have everyone Watch everyone else' accounts and repos
3. make sure
   • verify this, by making a commit_test folder in a corner of modex, having someone make a change, and seeing if everyone else gets it; rotate who makes the change until you're sure that github is sending emails to everyone and they're getting there.
4. (optionally) follow your github RSS feed (for those who already use RSS)
5. Get qgis installed on everyone's laptops
6. Get excel installed on everyone's laptops
