[gdal-dev] HDF5 product handling

[Alex Mantaut]

Thanks Frank, I will define product-specific methods just to fetch the
metadata in the open method.
I will use the hdf4imagedataset code as a guide on how to process the
metadata.(I didn't realized earlier that hdf4 implements something similar
to what I asked :P)

I still need to solve a few things before posting the patch, I look foward
incorporate the patch into the project.
