Detailed Description

Upward planarized representations (of a connected component) of a graph.

The upward planarization representation is a single source single sink graph. The single source is s_hat and the single sink is t_hat. s_hat is connected with the sources of the original graph. This muss be done before creating of a instance of UpwardPlanRep. The super sink t_hat is contructed in this class. For technical reason we contruct a sink t and connect the sink of the original graph with t. Then we connect t with t_hat. The edge (t,t_hat) is called the external face handle. Because the right face of the adjEntry of this edge should be the external face.
