Find emails in your Google Directory for names in a Google Sheet
* This is a script to look through column x for names,
* search your directory for email addresses for that name,
* and print them into column y.
* To get started:
* 1. Open an existing Google Sheet or create a new one ( and give it a name.
* 2. Click Extensions → Apps Script and give that new Apps Script project a name (e.g. "Lookup Email from Name").
* 3. Paste all of this code into that project.
* 4. Specify if it has a header row on line 19 of the code (true or false), as well as the name and email column letters on lines 20 and 21.
* 5. Click ➕ Services on the left sidebar, scoll down and select "Peopleapi", and click Add.
* 6. Click "▷ Run" in the top toolbar, allow authorization, and it should fill in the emails if it can find them!
