ITP - hashes - exercise - 1

Given a hash of family members, with keys as the title and an array of
names as the values, use Ruby's built-in select method to gather only
immediate family members' names into a new array.

family = {  uncles: ["bob", "joe", "steve"],
            sisters: ["jane", "jill", "beth"],
            brothers: ["frank","rob","david"],
            aunts: ["mary","sally","susan"]
}
