Description

This patch allows for group_by to take arrays. Example: 

!#ruby
Event = Struct.new(:title, :occurs_on)
events = [ Event.new("Cooking",["Mon","Tue"]), Event.new("Skiing","Mon") ]

events.group_by { |event| event.occurs_on }

{"Mon"=>
        [#<struct Event title="Cooking", occurs_on=["Mon", "Tue"]>,
         #<struct Event title="Skiing", occurs_on="Mon">],
 "Tue"=>[#<struct Event title="Cooking", occurs_on=["Mon", "Tue"]>]}

Ruby 1.9 includes a built in Enumberable#group_by. We want to stay compatible with that.
