(Swift 3/4) List all Folders

Demonstrates how to retrieve a list of all folders.

Note: Let's say we have a directory tree with the following folders in Google Drive:

/AAWorkArea
/AAWorkArea/FolderA
/AAWorkArea/FolderB
/Folder2
/Folder2/FolderA

This would be our result. Notice that the "name" of each folder is NOT the full path, but just the final folder name. To distinguish between the two FolderA's, we would need to get the parent information for each.

---- Page 1 ----
name: FolderB
id: 1ep8p9wsCV8S_xTI7G1-qEuf8RNO_9250
mimeType: application/vnd.google-apps.folder
-
name: FolderA
id: 1h_BWJGEn7L7aFV5SN8iOKv91uxddTbY8
mimeType: application/vnd.google-apps.folder
-
name: Folder2
id: 1cvDIF78KSDuUyrU_VCKRSRbmENWkHNqV
mimeType: application/vnd.google-apps.folder
-
name: AAWorkArea
id: 0BzXkF-yZEO0-ank3VndfZTZsdlk
mimeType: application/vnd.google-apps.folder
