• The primary conda environment is changed to notebook. It is the environment
  where the notebooks should be run. With this change, the dask extension should
  work naturally.
• Added the openvscode extension.
• Updates to prevent sessions with CPU activity from being stopped. The policy now is:
  • If there is CPU activity, the notebook will not be stopped, even if the browser
    is closed.
  • If there is no activity (e.g. the notebook or browser tab is closed),
    the session terminates after 15 min.
• The notebooks are updated automatically using nbgitpuller.
• Switched to using conda yaml files to keep track of the installed software.
