Attain Calculation Information per each Phase

After OptaPlanner completes solving, it logs timing information pertaining to each phase.  That is, after each phase (construction heuristic, local search, ...) phase, OptaPlanner logs the following information:

• time spent
• best score
• calculation speed
• step total

This information should be available via an API to the application for each phase.  That is, the calling application will get a list with each phase and the pertinent information for each phase.   Any additional information that may be available internally should also be considered.

The following is the output from OptaPlanner:
