h4h5tools

Purpose:
Add several attributes(class,title,version,field_name) to follow HDF5 table specification.
Description:
We encourage user to use H5TABLE high level interfaces so in h4toh5 conversion library, we
add a few attributes to recongnize the TABLE APIs. Users can still treat the converted Vdata as one D
compound dataset. It may be much easier for old HDF4 users to use Table interfaces.
