In its simplest usage, `Model.find()` accepts a query document (a JSON object) as the first argument, then a callback. It returns an array of matches. It supports an extremely wide range of search options. Read more in the docs.

Modify the `findPeopleByName` function to find all the people having a given name, using `Model.find() -> [Person]`
Use the function argument `personName` as the search key.
