* This Google Sheets script keeps data in the specified column sorted any time
* the data changes.
*
* After much research, there wasn't an easy way to automatically keep a column
* sorted in Google Sheets, and creating a second sheet to act as a "view" to
* my primary one in order to achieve that was not an option. Instead, I
* created a script that watches for when a cell is edited and triggers
* an auto sort.
