fyi.opensocial.getTabBundle

A tab you can see, as a template shared from it has it, for sharing it with everyone as yourself: its page, its methods and the kinds of record it makes up, the tab's namespace in them made the placeholder, and what a tab of it does. Its records are written in your own repo by you: a fyi.opensocial.templateVersion, each file a blob, and the fyi.opensocial.template listing it, at the record key given. Refused as shareTab refuses, and a new version whose kinds of record change in a way records already kept wouldn't fit.
