Extend System Designer to other languages

System Designer is for creating JavaScript systems. Anyway we can still use it for defining the model of any system implemented with other languages. Definition of schemas, modals, types and components are agnostics, so there is no dependency with a specific language.

But at runtime there is a decency with behaviors APIs. Adapting the runtime for other languages will mean to create a specific runtime for each language. This is not the purpose of System Designer. System Designer if for learning how to create systems and to make it them run.

So I will close this issue as:

• System Designer can be used with any language for modeling a system and
• creating a runtime for each language is out of the scope of the product.
