// Description:
//      Inherits from the abstract class PndTpcAbsPadShape
//      This class defines the shape of a pad by a vector of ordered points.
//      The user should to take care that the origin is almost circa in the
//      centre of the polygon (origins outside the polygon are forbidden).
//
// Environment:
//      Software developed for the PANDA Detector at FAIR.
