Will cause a NoMethoError when it tries to collect.

I have problems when I try to do something like this:

tweets = client.query(:q => 'ruby', :lang => 'en')
sleep 60
tweets << client.query(:q => 'ruby', :lang => 'en')
tweets.flatten!.uniq!

It fails to clear out duplicate items. Defining the following methods on TwitterSearch::Tweet fixes the problem:

def eql?(other)
    self.hash == other.hash
end

def hash
    @id
end
