Moves a file or a directory from a given path to another path.

This function's path is relative to the project root folder but it can also accept absolute paths.

All file separators should be forward ones "/".

Make sure to include the name of the files or directories at the end of the "to" argument.

	// creates a menu entry to move a file or a directory.
	@MenuItem ("Example/Move Something")
	static function MoveAFile () {
		// moves the file "YourFileOrFolder" from "path/" to "movepath"
		FileUtil.MoveFileOrDirectory("path/YourFileOrFolder", "movepathYourFileOrFolder");
	}
