Made dependencies the same for serial and parallel,
can check with make depends and make depends_parallel,
dependencies and dependencies_parallel should be the same.
Modified fortran with -I/usr/include for gfortran compiler
to find mpif.h.
Now use mpif.h in mpimod.F90 to define MPI_COMM_WORLD.
Dictionary.h moved in cxx files to make serial and parallel
dependencies the same.
Ifdef'd mpimod to exclude everything in module for serial version.
