title: Merging two noteboooks into one in Jupyter (ipython)
body: <p>I have two different Jupyter notebooks for two different projects. I would like to merge them to get them both on the same notebook.</p>
  
  <p>One way is to copy cells from one to the other one but it seems to be quite a bit of work for projects containing many cells. Is there a feature supporting importing Notebook documents or copying multiple cells at a time?</p>
