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
Perhaps this can be more succinctly written as:

```cs
            var query = CurrentWorkspace.Nodes.Where((n) =>
            {
                return n.GUID.Equals(nodeId) && n.Name.Equals(node.Name);
            });

            if (query.Any())
                return query.ElementAt(0);
```
