Detailed Description
Normal straight line segment in a2dVertexList and a2dVertexArray.baseclass for segments in a a2dVertexList and a2dVertexArray Every segment type in a a2dVertexList and a2dVertexArray has this class as Baseclass. It has/maintains the end position of a segment. But for the first point it is a2dVertexList and a2dVertexArray to give the begin point too.
