MPI support currently uses blocking send and recv MPI calls. In the future, we will add non-blocking send and recv calls. Currently, the MPICommUtils class will spin a listener thread for every node that listens for a receive request from another node. Once that request is received by the sender node, the sender node will send the requested information to the receiving node on the listener thread while the main thread continues to train. MPI support has been tested using 10 and 100 samples per node, 3 + 1 nodes and up to 10 rounds. |

Issue #96
Added MPI Communication class to support MPI in a truly decentralized system. Server will listen for requests and send information when request is received. Client will send a request and receive the response. The methods in this class are non-blocking.
