Simple AndroidX Migration Script

	#!/usr/bin/env bash

	# I've found that the "Migrate to AndroidX" converter in Android Studio doesn't work very
	# well, so I wrote my own script to do the simple job of converting package names.
	#
	# You can download a CSV of package names here: https://developer.android.com/topic/libraries/support-library/downloads/androidx-class-mapping.csv
	#
	# It'll run faster on a clean build because then there are fewer files to scan over.
	#
	# Uses `gsed` because I'm on a Mac. Can easily replace with `sed` if you don't have `gsed`.
