Hyphen in container names

[ambsw-technology]

Got confused and thought I had reported it in a different issue when it was actually new. I ran into a linking error and it turns out that it was related to #15. I changed the container name to eliminate a hyphen the problem resolved itself. If you go back to the same thread referenced in #15, it looks like there's a toxic interaction between EVN variables (no hyphen) and network names (no underscore) that's working its way through the docker consciousness.

I'm not sure if there's a local fix -- except raise a useful exception -- until they get the conflict sorted out internally.
