[magwas]

Behaviour: Schulze method/normalize beat matrix;the diagonal elements are (0,0)

@tested_feature("Schulze method")

@tested_operation("normalize beat matrix")

@tested_behaviour("the diagonal elements are (0,0)")

A testable aspect of function: a set of pre- and postconditions.

Deviation in model

The diagonal elements have no meaning, none of the result computational algorithms uses them, hence it is unnecessary to store zeros.
