Some times IRR can not find the right value.

[Teddyzhu]

Brent(AbstractSolver1D) solver will cross the -1 and then will cause IRR no meaning.

==================
Steps to Reproduce
==================
Sorry, I will forget the test data. We use this function to simulate the goal-seek feature of ms excel for IRR. And then find this issue.

Fix
File: CashFlows.java line 350:

         final Brent solver = new Brent();

+ if(Compounding.Compounded.equals(compounding)){
+ solver.setLowerBound( tolerance - 1 );
+ }

         solver.setMaxEvaluations(maxIterations);
