BairstowRootFinderFindUniqueRoots(IListBairstowRootFinderSolveResult, Double) Method

Extracts the unique roots from the list of all roots resulting from Applying Bairstow's method to find all roots of a polynomial. Equality is determined by the "relative error" between the two values, x and y, being compared according to the formula: E = ||x - y||, if max(||x||, ||y||) is less than 1 ||x - y|| / max(||x||, ||y||), otherwise
