Modification
Description:
Put some of the variables into the global space so that random
functions can access them. (The output and timer variables which
point to the output file and timer resp.)
Placed the debug level 4 prints into the timer module so that it's
easier to automatically put timer start/stop printfs for new timers
which are created.
Added timers for MPI Time calls (called HDF5_MPI_WRITE and
HDF5_MPI_READ).
