#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
