    Hama 900 - Added a new strategy to schedule tasks based on round robin scheme

    In this pull request, I have implemented the TaskAllocationStrategy to schedule tasks
equally on cluster. 
    I ran multiple tests on my cluster including the PI example and my own algorithm and everything
was alright. 
    Following snapshot shows one such example. On my cluster with 9 machines supporting 54
tasks, I ran a job with 18 tasks. In the screenshot you can see the equal distribution in
cluster with each machine only running 2 tasks.
