areSymmetric()

static bool areSymmetric ( const AWeightedRelations &  weightedRelations )

Checks for the symmetry of a range of weighted relations Explicitly checks for each weighted relation, if their is an reverse relation with the same weight.

Returns true if all such inverse relations exist.
