/**
 * Classes to enable distributed computing.  Algorithms that are naturally
 * parallel can be parallelized using this package without altering the 
 * algorithm.  This is feasible using the {@code Future} concept of blocking
 * only when attempting to read the result and the evaluation has not yet
 * completed.  As long as the algorithm submits multiple jobs to the 
 * {@code evaluate} method prior to reading the results, the objectives 
 * and constraints, the algorithm is naturally parallel.
 * <p>
 * To use, an {@code ExecutorService} is required that will distributed the
 * jobs to asynchronous threads, cores or compute nodes.  Java frameworks such
 * as <a href="http://www.jppf.org">JPPF</a> and 
 * <a href="http://www.gridgain.com">GridGain</a> provide 
 * {@code ExecutorService} interfaces out-of-the-box.  Then, the desired
 * {@code Problem} is decorated with the {@code DistributedProblem} to enable
 * parallel execution.
