Notes:
- When a process reaches this automated step, "multi-line text" is automatically processed.
    - Each line of multiline text is tested with RegExp, and only lines matching the condition are output.
    - Note that it is possible to store not only filtered-down lines, but also filtered-out lines.
- If the amount of calculation is too large, the process will be terminated in the middle.
    - A large number of Lines or complex RegExp that requires more than 30 secs will result in a termination.
- No line feed code is inserted at the end of the output string.
    - "Narrowed Text" (filtered down)
    - "Removed Lines" (filtered out)
- Various human steps can be automated (unmanned).
     - Filter by date
     - Remove invalid email addresses
     - Remove invalid zip codes
     - Extract URLs starting with "http://"
     - Extract only jp domain URLs

Notes-ja:
- 案件がこの自動工程に到達した際、「複数行テキスト」が自動的に加工さます。
    - 複数行テキストの各行がそれぞれ指定した正規表現でテストされ、条件にマッチした行だけが出力されます。
    - なお、フィルタ抽出された行だけでなく、フィルタ除去された行を格納することも可能です。
- 計算量が多すぎる場合、途中終了します。
    - 行数が多い・正規表現が極めて複雑など、30秒を超えるような処理は途中で終了する可能性があります。
- 出力文字列の末尾に改行コードは挿入されません。
    - "絞り込まれたテキスト"
    - "除去された行"
- 様々なヒューマン工程を自動化（無人化）できます。
    - 日付を絞り込む
    - 不正なメールアドレスを除去する
    - 不正な郵便番号を除去する
    - "http://" 始まりのURLを抽出する
    - jpドメインのURLだけを抽出する
