MPI version

Each node computes and stores angular data on disk independently from the other nodes, no communications are required. The program structure of the parallel version has not changed compared to the serial version. Only some of the routines have been modified and they mainly differ from their serial counterparts in included additional statements for I/O output. For all MPI modified files an mpi_ prefix has been added. Except for the presence of initializing and finalizing MPI communications, each MPI node independently processes the configuration list by columns, using interleaved mode with a step equal to the number of processors.
