/*
  This class implements a rectangular maze
  with width fields in horizontal direction and
  with height maze fields in vertical direction.
  A maze field is rectangular and can have walls and borders at its edges.
  The maze has to be initialised with all walls blocked
  and some of these walls can be removed for building a maze.
  The outer rim of the maze has to be defined by borders.
  Borders are also allowed within the maze to exclude certain fields from the maze.
  Borders must have walls.
  Maze fields outside the outer borders must not have walls.
