This example is somewhat confusing on UNIX since the directory
used does not exist on my system, or indeed on most systems.
The result is an empty list of files, making me think that
the example is broken.
I have attached a version which uses the last argiment on the
command line if that argument is a diretory, otherwise $HOME.
The code would be a little cleaner if createApplication() had
easy access to a sanitized argc/argv. By that I mean argc/argv
that when the application is invoked as e.g.
./filetreetable.wt --docroot . --http-address 0.0.0.0 --http-port 8080 /tmp
it would look as if the invocation had been
./filetreetable.wt /tmp
