New Capability: Reactive Message Handling Flow [Enhancement]

[TaviTruman]

I'm suggesting this new capability based on a couple of years of developing WPF apps with GE Client capabilities with particular support for MVVM and Semantic-powered process substrates.

Extended the Trinity Networking protocol layer to formally support Reactive Message Handling flow. I am able to implement this capability via the following:

• Specify Type: Asyn in the TSL
• Specify Response: int in the TSL * Must do so that we can await the method call!
• Add new Keyword Reactive with Payload Type
• Code gen should create IObserver and IObservables in the base class
• Add formal and stronger API semantics for Publish, Subscribe and extend the Request and Response code generation policy for sold API semantics. Code generation should use Reactive Design patterns for Server and Client-side use.

Call "CallBack" reserved work to TSL Protocol scheme:

// Server-side Push/Publish to Client
protocol PushTripleToClient
{
Type: Asyn;
Request: TripleGetRequest;
Response: ErrorCodeResponse;
CallBack: OnGetTripleRequestCompleted;
}

This can be closed now; I have solved the problem without the need to add new code to the library
