PhSim Editor has been updated

I have updated the PhSim editor. Here are the changes:

  • It uses phsim v0.2.1-alpha (see the changelog for more details).
  • I have created a help page for objects.
  • I have added links that look like question marks in strategic locations. These links give help to those who are using the PhSim editor.
  • I fixed several bugs in the PhSim editor.
