Directory Watcher

Modified Java directory watcher example, made to be generic and useful.

Changes

• Allow for a callback to be executed when a file/directory event is triggered
• Allow for path filtering from commandline
• Allow for notifications to be passed to executables (%file% and %event%)

Example

java -jar DirectoryWatcher.jar -watch /Users/joshes/test -filter ".*?sub_dir\/?.*?" -callback "echo '%event% - %file%'"
