// Abstract:
// This script is just a quick hack to export the owners and members of a team as a CSV file without administrator permissions.
//
// Usage:
// 1. Open your team
// 2. Select "Manage team" from its menu
// 3. Select the "Members" tab
// 4. Expand the "Owners" and "Members and guests" sections
// 5. Make sure to scroll down to the end of the owners and members lists to include all of them in your export (As the members are loaded on demand)

I like to call foldr as "fold from the right", while foldl is "fold from the left".

// I've tried to capture interesting suggestions here.

HotPlate

You have a 16x16 grid of which the 4 centermost cells are always 100 degrees and the cornermost cells are always 0 degrees. All other cells start at 50 degrees.

For example, a 6x6 grid would look like this:

|  0  | 50  | 50  | 50  | 50  |  0  |
| 50  | 50  | 50  | 50  | 50  | 50  |

| 50 | 50 | 100 | 100 | 50 | 50 |
