AOT compilation failing

It would be nice to be able to deploy a "production" version of the prototype on the server. Currently we can only run a "development" version because we get template binding errors if we try to use AOT. See https://angular.io/guide/aot-compiler

**The goal is to be able to run "ng serve --aot"** (or "ng build --prod"), just try it to see where we have errors.
