title: create a Google spreadsheet in a particular folder
body: <p><a href="https://stackoverflow.com/questions/13532114/google-apps-script-addtofolder-adds-to-folder-and-mydrive">this question</a> teaches how to adjust the folders of a file to move it into a particular folder, and out of the root.</p>
  
  <p>It also suggests using folder.createFile to create it directly in the desired folder... but it appears createFile only applies to Docs... is there a way to create a spreadsheet directly in a particular folder?</p>
