A python crawler downloads notes from clearnotebooks.com

   choose one note you like on www.clearnotebooks.com

   the note_id is on the tail of the note's url

   like this :
          https://www.clearnotebooks.com/zh-TW/notebooks/737837

   and the note_id is 737837

   input the note_id and the crawler will help you download all of pages in ".jpg" image file

   and it will build new folder by the tag from clearnote website

   it make notes more easy to sort out

   why we need the crawler :
          beacause it is too slow viewing notes on thier website
