Major Improvements
Memory leak fixed in the HDF-Java native.
Added H5.getOpenIDCount() and H5.getOpenID() to track any open IDs.
These functions can be very useful for checking memory leaks for
applications.
Added features to show data pointed to by object references
and region references.
Added find/search dataset from HDFView.
Added user option to open a file directly with read-only mode.
It now shows unsigned 64-bit integer.
It supports netcdf3 files for the NETCDF module (ncsa.hdf.object.nc2.NC2File).
