描述----------Description----------
A bipartite representation of a hypergraph. The purpose of this class is to support visualization of the hypergraph; it is not intended for analysis or manipulation
一个一个超偶代表。这个类的目的是支持的超图的可视化分析或操纵它不打算
类的对象----------Objects from the Class----------
Objects can be created by calls of the form new("graphBPH", graph, edgeNodePattern, ...). There is also a convenience function graphBPH().
创建对象可以通过检测的形式new("graphBPH", graph, edgeNodePattern, ...)。还有一个方便的功能graphBPH()。
A graphBPH object consists of a graphNEL object, which must obey some strict rules:
一个graphBPH对象包括graphNEL对象，必须遵守一些严格的规则：
nodes in the graph are divided into two sets: normal nodes and edge-nodes,
图中的节点分为两组：正常节点和边缘节点，
all edges in the graph must connect a normal node to an edge node,
图中所有的边缘都连接到边缘节点的正常节点，
the graph must be a directed graph.
图形必须是一个有向图。
The edgeNodePattern is a regular expression that is used to define the set of edge-nodes.
edgeNodePattern是一个正则表达式，用来定义边缘节点的集合。
插槽----------Slots----------
graph: Object of class graphNEL. This graph
graph类graphNEL的对象。此图
edgeNodePattern: Object of class character.
edgeNodePattern类character的对象。
nodes: Object of class character.
nodes类character的对象。
edgeNodes: Object of class character.
edgeNodes类character的对象。
edgeNodeIO: Object of class list. Records information about which edges enter and exit
edgeNodeIO类list的对象。记录的信息，哪些边缘的进入和退出
方法----------Methods----------
plot signature(x = "graphBPH"): draw a representation of the hypergraph where edges between normal nodes in the graph pass through an intermediate
图signature(x = "graphBPH")：这里边画一个超图表示图通的正常节点之间通过中间
graphLayout signature(graph = "graphBPH", layoutType = "missing"): convert the graphBPH object to a RagraphBPH object (using a default layout method).
graphLayoutsignature(graph = "graphBPH", layoutType = "missing")：graphBPH对象转换成一个RagraphBPH对象（使用默认的布局方法）。
graphLayout signature(graph = "graphBPH", layoutType = "character"): convert the graphBPH object to a RagraphBPH object (using the specified layout method).
graphLayoutsignature(graph = "graphBPH", layoutType = "character")：graphBPHRagraphBPH对象（使用指定的布局方法）对象的转换。
