BUG: 0005493 - This seems to fix the vector writing and read back issues with Paraview saving Xdmf.

ENH:Added a SetTimeValue method, for supporting multiple time steps in the same xdmf file.
Added lag AppendGridsToDomain, to allow multiple grids into one file.
Added a flag InputsArePieces, this allows blocks(pieces)  to be added one by one and then all written as one large dataset.
Added FullGridSize  method to support piece writing.
Various other small bug tweaks addressed with extents and hdf5 read/write issues
