#2221:

• Completely refactored PTSP branch
  • Added two sets of problem instances based on TSPLIB: homogeneous and heterogeneous
  • Implemented missing EvaluateByCoordinates for 1-shift moves
  • Made it clear that move evaluators are for estimated PTSP only
  • Changed parameter realization from a rather strange list of list of ints to a list of bool arrays
  • Reusing code of the 2-opt and 1-shift move evaluators in 2.5 move evaluator
  • Introducing distance calculators to properly handle the case when no distance matrix is given (previous code only worked with distance matrix and without only with euclidean distance in some settings)
  • Fixed several smaller code issues: protected, static, method parameters, copy & paste, interfaces, naming, parameters, serialization hooks, license headers, doc comments, data types
