A complete refactoring of TrustRegionMinimizer.

1. Break up the monolithic loop in TrustRegionMinimizer::Minimize
   into a number of more easily described and analyzed subfunctions.
2. Break out the logic for evaluating the quality of a Trust Region
   step into its own object - TrustRegionStepEvaluator.
