Corrected saveObjects call example (#702)
Corrected saveObjects call example (#702)

The provided example used a single dimensional array as an argument for the `saveObjects()` method.
As saveObjects saves an array of objects, it generated an error.
I updated the example to use a single `saveObject()` method, which I find easier to understand as a beginner than a two-dimensional array argument for `saveObjects()`
