/*
  the idea behind this class is to avoid a mix of persistent value and
  volatile values in CAtmoConfig class because some parameters and variables
  exists only for the current process and won't be stored to the registry

  (Simple thought its a container... )

  you ask? why I didn't used a struct for it? ..mmh I like classes?

  Problem: MultiThreading! todo semaphore, mutex!

  Allways stop the current effect Thread before changing AtmoConnection or
  AtmoConfig!
