 A solver may require that the interval brackets a single zero root.
 Solvers that do require bracketing should be able to handle the case
 where one of the endpoints is itself a root.solve in interface BracketedRealFieldUnivariateSolver<T extends RealFieldElement<T>>maxEval - Maximum number of evaluations.f - Function to solve.min - Lower bound for the interval.max - Upper bound for the interval.startValue - Start value to use.allowedSolution - The kind of solutions that the root-finding algorithm may
