Implement the TOPSIS[0] algorithm to score multi-valued alternatives
according to a given set of weighted criteria.

The number of alternatives cannot be known at compile time, but the
number of criteria should be (a given module using the topsis module
should have one (or more) fixed sets of criteria). Therefore, the
TopsisMatrix is implemented as a Vec of N_CRITERIA-sized arrays.

Compared to the description in [0] the weighing of the matrix
according to the weights of the criteria only happens during distance
calculation to the idealized alternatives. It turned out more natural
like that, because the matrix doesn't need to be mutable.
