DBOPT_APPEND_START, CONTINUE, FINISH options for silo objects (HDF5)

[aowen87]

cqid: VisIt00007439cqsubmitter: Mark Millercqsubmitdate: 08/09/06 User would like to be able to build up his ucd mesh and variables on disk by appending more nodes and zones in multiple calls. I wouldn't like to try this on the PDB driver (though I think PDB could support it). However, I think we could make it work on the HDF5 driver. If we had DBOPT_APPEND options to specify the beginning, intervening and final calls to write the object(s), we could create extendible datasets in HDF5 and it would work pretty smoothly, I think.
