> There is partial overlap of functionality between class {{RootsOfUnity}} and method {{nthRoot}} (in class {{Complex}}).
> The latter is more general (any complex number) but the former allows a negative argument (to specify clockwise ordering).
> Also, the implementations are different; it should be checked which is more accurate (and then account for possible performance trade-offs).
> API-wise, I think that we should keep {{nthRoot}} (and delete {{RootsOfUnity}}).
