Allows you to watch contents of a directory for file changes.
Add DirectoryWatcher to your scene, register a directory and connect signals. It will automatically notify you of added, removed or deleted files.
var watcher = DirectoryWatcher.new()
Change 'scan_delay' property to control scanning period (default is 1 second) and 'scan_step' to control scanned files per frame (default is 50). The watcher will go through the file list in a directory and emit the signals at the end of the cycle.
Includes built-in documentation. Check the repo page for more details.
