  *  \section      sTechnologyIntro  Introduction
  *
  *                The Technology object provides the description of all the technology
  *                rules needed by the tools, currently it is limited to the description
  *                of all layers available. This object must be created once within the
  *                DataBase, and, in principle never destroyed (this would destroy layers
  *                and all objects laying on them ...).
  *
  *  \remark       There is only one technology for the current DataBase, and only one
  *                Database object, so only one technology defined.

  *                notably for the graphical display. Therefore deeper
  *                basic layers must be created first and upper layers
  *                later (the order of composite layers has no
  *                importance).
