 #Kind of an automatic listing of the services created by the running docker containers
 #Like Apache Fancy AutoIndex, but for docker services that have mapped all the way out to host port.
 #todo: 
 # - expand well known services handling / alternative urls
 # - loop to automatically refresh
 # - error handling
 # - pseudo clever service probing to see if we can figure out more about what is actually served up. 
 #     If actually http, then maybe even traverse HTML for title tags and meta decription tags?
 # - automatic publishing copy to /var/www/html if it exists?
