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
Could ```JsonSettings``` be made non-static class data member? After previous rounds of memory leak issues we had in Dynamo, I'm trying to avoid static instances of objects lying around Dynamo if possible. We can initialize this data member before it is used if it is ```null```.
