The AddClass method

The AddClass method of the KnowledgeGraph class takes class as a parameter and returns true if the class exists. If the class does not exist, a GraphNode is created with class as a key:

// AddClass methodfunc (knowledgeGraph *KnowledgeGraph) AddClass(class Class) bool {  var exists bool  if _, exists = knowledgeGraph.GraphNodes[class]; exists {    return true  }  knowledgeGraph.GraphNodes[class] = struct{}{}  return true}
