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
It seems like if the ```Main``` method here does not need to care about ```/c``` or ```/server``` command flags, when it is run, it will always enable the server.
