1) Implement ComputationResult response with the node data which was changed after execution of RunCancelCommand (values, geometry)
2) Add REST service to retrieve static data (for now it is the list of Node Models)
3) Update models drawing logic to avoid Dynamo crash on subsequent client updates
There is a code duplication here, can we refactor the ```MakeSandboxAndRun``` above to do something like this:

```cs
public static Application MakeSandboxAndRun(string commandFilePath, bool turnOnServer)
{
    // Call your version of 'MakeSandbox'
    var ui = MakeSandbox(commandFilePath);

    if (turnOnServer)
        dynSettings.EnableServer();

    var app = new Application();
    app.Run(ui);
    return app;
}
```
