/**
* Uses the RuleServiceProviderImpl for Drools to solve the Miss Manners
* problem.
*
* Miss Manners is a program which handles the problem of finding an acceptable
* seating arrangement for guests at a dinner party. It will attempt to match
* people with the same hobbies, and to seat everyone next to a member of the
* opposite sex. Manners is a small program, which has only few rules, and
* employs a depth-first search approach to the problem.
