Version 0.7

New method: ELECTRE2.
New preprocessin strategy: A new way to transform from minimization to
maximization criteria: NegateMinimize() which reverses the sign of the
values of the criteria to be minimized (useful for not breaking distance
relations in methods like TOPSIS). Additionally the previous we rename the
MinimizeToMaximize() transformer to InvertMinimize().
Now the RankingResult, support repeated/tied rankings and some were
implemented to deal with these cases.
- RankingResult.has_ties_ to see if there are tied values.
- RankingResult.ties_ to see how often values are repeated.
- RankingResult.untided_rank_ to get a ranking with no repeated values.
  repeated values.
KernelResult now implements several new properties:
- kernel_alternatives_ to know which alternatives are in the kernel.
- kernel_size_ to know the number of alternatives in the kernel.
- kernel_where_ was replaced by kernel_where_ to standardize the api.
