#1215

  • lots of memory-consumption improvements
  • validValues -> validTypes (this saves memory!)
  • changed manipulators; modifications are less significant, out-of-bound-values are resampled instead of set to lower or upper bound
  • changed the way a base-level algorithm gets executed -> introduced AlgorithmExecutor
