/**
 * 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.
