  * The class consists of three basic functions that determine the angle between two lines,
  * the distance between the lines and the common part of the lines. First, all input lines
  * are checked if there is a second line running in the same direction. Thereafter, all line
  * pairs that already fulfilled the angular criterion are checked whether they are close to
  * each other or not, i.e. the orthogonal distance between them is calculated. Finally, it

  * A possible processing chain would be to extract lines with a line detector, to convert the
