Created October 27, 2021 19:41

Convert the files in a directory from space-indented to tab indented detecting the indentation level automatically

	''' TABBER: Because spaces suck

	This script will recursively convert all files in its directory from space indented to tab indented.
	It will detect the number of spaces used for indentation and transform them into tabbed files.

	Usage:
	1. Copy the directory you want to convert and put this file inside. If you're brave enough, skip the
	copying part.
	2. Review the EXTENSIONS and IGNORE_FILES values.
	3. Run it.
