refactor iteration to use map

current.rb

def following_pages
  twitter_user.friends_count.to_i / 100 + 1
end

def following
  @following ||= (1..following_pages).map do |i|
    twitter.friends_for(uid, :page => i, :lite => true)
  end.flatten
end

def followers_pages
  twitter_user.followers_count.to_i / 100 + 1
end

def followers
  @followers ||= (1..followers_pages).map do |i|
    twitter.followers_for(uid, :page => i, :lite => true)
  end.flatten
end
