> Demonstrate how the developer/user can create a custom FEEL function to access to the DMNRuntime.
> This in a target application can serve several use cases:
> * *Introspection*. For instance return information about the environment, like number of models etc.
> * *Access to Kie API*. For instance to call out to a Stateless Kie Session execution in the same application. (The DMN user is knowledgeable by the spec external invocation shall be side-effect free)
