Thanks,
Opening the dev tools showed me that my server was having trouble fetching code from code.jquery.com (due to firewall issues that have been fixed).
Now it gets farther in the Atlas load process, but displays the following error messages:
application initialization failed
unable to connect to an instance of the webapi.
please contact your administrator to resolve this issue.
The tomcat log shows the following:

I believe the config-local.js example given in the install instructions has a bug in it. It specifies an HTTPS url
url: 'https://localhost:8080/WebAPI/'
When I change this to http and load the application the web page seems to load correctly.
url: 'http://localhost:8080/WebAPI/'
