Watch a directory recursively
TreeSpy spy = SpyFactory.getSpy();
String directory = "/home/wfaithfull"
File home = new File(directory);
spy.watchRecursive(home, (changedFile, eventType) -> {

});Watch a directory recursively with a glob pattern
TreeSpy spy = SpyFactory.getSpy();
String directory = "/home/wfaithfull"
File home = new File(directory);
spy.watchRecursive(home, (changedFile, eventType) -> {

}, "glob:*.java", "glob:*.txt");
