The section about publish-mode is confusing

[pdg744]

I felt quite confused reading this section. It felt like there was a disconnect between the heading and the text of the section; not clear immediately what "publish" means or how the words in the section connect to the phrase "publish mode."

Some concrete suggestions:

• [ ] Introduce/define the term publish. As of this writing, the term only appears in a section heading and a code snippet.
• [ ] Consider dropping the term publish-mode; the current name implies publish only, while the text of this section reflects call Bonsai from off-chain and then publish.
• [ ] Consider moving this section (and the previous section?) out of the ## Testing your Program section
• [ ] Revise to reflect user oriented framework of ## call bonsai from on-chain and ## call bonsai from off-chain

I just learned that #29 revises a lot of the relevant details here; will re-visit after #29 lands to see if these issues still merit attention.
