public class BrentSolver extends AbstractUnivariateSolver
solve method returns a zero x of the function f
 in the given interval [a, b] to within a tolerance
 2 eps abs(x) + t where eps is the relative accuracy and
 t is the absolute accuracy.
 The given interval must bracket the root.
The reference implementation is given in chapter 4 of
Algorithms for Minimization Without Derivatives, Richard P. Brent, Dover, 2002
