Use Evaluation instead of PointVectorValuePair in the ConvergenceChecker. This gives the checkers access to more information, such as the rms and covariances. The change also simplified the optimizer implementations since they no longer have to keep track of the current function value. A method was added to LeastSquaresFactory to convert between the two types of checkers and a method added to LeastSquaresBuilder so that it can accept either type. I would have prefered to do this through method overloading, but overloading doesn't play well with generics. git-svn-id: https://svn.apache.org/repos/asf/commons/proper/math/trunk@1569353 13f79535-47bb-0310-9956-ffa450edef68
