[svn-r7838] Purpose:

    Bug fix and File Addition

Description:
    - Fixed when reading from the file with FPHDF5. It wasn't recording
      how many bytes it read.

    - Added Arithmetic Transformation modules. These haven't been
      included into the HDF5 build. I just added them here for future
      porposes...

Solution:
    Added a call to "MPI_Get_count" to get the number of bytes read.

Platforms tested:
    Linux (w/ FPHDF5)
    AIX (w/ and w/o FPHDF5)

    FPHDF5-specific fixes...No need for H5committest
