(Orthogonal)Summation now goes level-wise.

  • print(Orthogonal)Sum go through all levels and call on (Orthogonal)Summator to get value which is stored in vector of result of MapType.
  • (Orthogonal)Summator hands on level to (Orthogonal)Summation
  • (Orthogonal)Summation::operator() and Sum() now require level as parameter.
  • NOTE: We cannot set the value to zero (this depends on the default cstor). If level==0, then we return an uninitialized value.
  • Renamed print(Orthogonal)Sum -> AllLevel(Orthogonal)Summator.
  • Property mode set to 100644
