Implemented two halo exchange routines: one uses an MPI vector datatype and the other manually packs and unpacks the send and recv buffers. The MPI datatype method is not currently working due to a "double free" error in libc. The manual buffering method has been debuged and works.

* H5Block: added attribute writing functions to code generator: still need to add reading functions
...
* H5MultiBlock: added halo exchange routine: still needs debugging

0e853656cd
* fixed bug in h5bl_defin3dchunkdims call that was using variables addresses ins
...
* added new MultiBlock module that is used for efficiently loading regular
rectilinear grid blocks (using chunking) and handling ghost zones in a
distributed-memory environment
** still need to add the "halo exchange" routine for reshuffling ghost regions
** performed some basic testing of read/write functionality
