This prototype was apparently created by Matt Cechini.

John Dalbey found it in the git repository in a barely working state in Mar 2019.
Perhaps HTML and browser standards had changed since it was originally
created but a lot of major functionality was broken.

Importantly, the LoadEvents.js module was created to read the actual
Incidents Script (XML) and parse it into the internal classes used by the application.

A page for CAD Terminal was replaced by Current Event.  
Confusing map buttons were replaced by radio buttons.
