Update model201-016 on the server

Make the server changes necessary to finish implementing the 201-016 template assignments created by @qubd (PR #39).

• [x] create the link in the model course:
  • link model201-016/templates/Template_201-016 to .../Course-Templates/model201-016
• [x] delete all the old template assignments from the 201-016 model course
• [x] test that all is working nicely
  • this testing can only happen after the CPL updates are pulled from GitHub, which won't happen before the end of the Winter Term
• [x] (stretch goal) Set up the 201-016 model course to simulate the effect of the linking and CPL update above. This would allow some testing before the end of the Winter 2022 term.
