Things To Do

 Some libraries add state: shared state and process global state.  How do manage this?
+
+When a library is included into a model, it may add shared variables to the model.  When it is attached to a process it may add process-global variables.
+
+Define class Library, LibraryFunction.
+
+attachToModel(ModelIF);
+attachToProcess(ProcessIF);
+
+in ModelIF, ProcessIF, etc.: getFunctionWithName("fprintf") will return the function if it has been added.
+
+FunctionIF: boolean field: isSystemFunction.   If true, function does not have body (locations).  Instead, a special class will be loaded to execute this function's transformation of the state when it is invoked.
+
+add module library, submodule of model.
+also add system level function definition in semantics, next to Executor.
