Create 0.2.0 release

[jashapiro]

With the addition of #78, #77, #84, #85 and (pending) #87, we have made a number of pretty big changes to the workflow (especially the step-skipping of #77 and #87) , and this seems to me to justify a bump up to version 0.2!

We will want to make this version update/release before we do the bulk mapping, as we want those metadata to reflect a real release.

@allyhawkins If there are any other issues that you think might block this release, please let me know in a comment and/or add them as dependencies above!

I think this looks good and that we are good for the new release once we have #87 merged.
