hypergraph data model
概念（notations）:
超图由⾮空的顶点集和超边集组成(a hypergraph consists of a non-empty set of vertices and a set of hyperedges)
超边是⼀组有限的顶点集合(通过它们在超边中所扮演的特定⾓⾊来区分)(a hyperedge is a finite set of vertices (distinguishable
by specific roles they play in that hyperedge))
超边本⾝也是⼀个顶点，可以由其他超边缘连接(a hyperedge is also a vertex itself and can be connected by other
