Provides built-in ranking and transformers to apply to the current workspace. For instance for nodes, ranking can be the degree of the node or a numerical value like an 'age' or 'duration'. By default, the RankingModel have 'Degree', 'InDegree', 'OutDegree' and one ranking per numerical attribute. Ranking exists for both nodes and edges and these are called element types.
