An interactive programme for Steiner trees
  We introduce a fully written programmed code with a supervised method for generating Steiner trees. Our choice of the programming language, and the use of well-known theorems from Geometry and Complex Analysis, allowed this method to be implemented with only 747 lines of effective source code. This eases the understanding and the handling of this beta version for future developments.
