i followed existing style; lots of places has single-line ifs without curls. ex:

			if(threadData->entityTypeIndicator == TypeNode)
				parseNode(threadData);
			if(threadData->entityTypeIndicator == TypeWay)
				parseWay(threadData);
			if(threadData->entityTypeIndicator == TypeRelation)
				parseRelation(threadData);
			if(threadData->entityTypeIndicator == TypeDenseNode)
				parseDenseNode(threadData);

i personally think this style is ok. but as long as we agree on a style i can live with curls.
