Twitterのrepliesなどを複数ページ取得

呼び出し例

#!/usr/bin/env ruby
require 'TwitterAPI'

user = ARGV.shift
pass = ARGV.shift

api = TwitterAPI.new(user,pass)
api.replies(1,3).each{ |e| # 1-3ページを取得
  puts e.url
  puts e.content
  puts e.last_updated
}

replies()の他に、friends_timeline()とpublic_timeline()がある。
引数なしで呼び出すと1ページ目だけ読む。
