* 'clarifying the return value of findOrCreate'

The documentation of findOrCreate previously had no precise indication of what to expect findOrCreate to return. I added that it returns an array with two parts in the comments that had already existed in the examples.

* minor typo fixes

* Made some wording changes for tense
