Automatic JS AI Tool Calling with Supporting JS Sources

Demonstrates an automatic JavaScript tool function calling where JavaScript code can be loaded from additional scripts that don't include a tool registry. Lianja

// When evalOnly equals .T., it tells Chilkat that no toolRegistry will be present.
