Actor connections

[cjcodeproj]

Consider a proof of concept tool that would identify connections and relationships between actors.

For example, if comparing Bob to Alice who have never been in a movie together, identify the common actors in between them.

Benefits:

• Get more use out of existing data structures.
• Figure out a mechanism to pass an actor name on the command line.
