branch: 1.1-phetio

Start by reviewing the 1.1-phetio branch and the git history for the listed 1.1 versions, then compare those records with the bayes directory listing. Determine why the branch and versions exist, whether clients or the PhET-iO spreadsheet depend on them, and document the unexplained version and commit discrepancies.

In https://github.com/phetsims/function-builder/issues/139, I was attempting to publish a new version of Function Builder. The published version is 1.0.x, so I was expecting to be publishing 1.1.x. But when I went to publish the dev version of Function Builder, it was 1.2.x. Investigation revealed a 1.1-phetio branch and many 1.1 versions published to bayes. That resulted in a lot of confusion and a significant detour.

It looks like @samreid, @zepumph, and @jonathanolson were involved in this. As the responsible dev for this repo, please help me understand (or remember) what is going on here.

There is no 1.1 branch, but there is a 1.1-phetio branch. I'm not sure who created it.

function-builder has no PhET-iO instrumentation, and brand=phet is not enabled in package.json.

Here are the 1.1 versions on bayes, annotated with who published them (according to git history):

Questions:

• Why was this branch created? What PhET-iO work was involved?

• Are any of these versions used by clients, being maintained, in the PhET-iO spreadsheet, etc?

• If these versions were published from 1.1-phetio, why is the syntax for these version numbers all over the place? And I'm not clear on how we got version numbers with "1.1.x-dev.x" syntax when there is no 1.1 branch.

• 1.1.0-dev.3/ and 1.1.0-dev.4 have no associated commits. How could that be?

• I see git history for these 1.1 versions that do not appear on bayes. How could that be?
