Copy object from source location to destination location
H5O.copy(src_loc_id,src_name,dst_loc_id,dst_name,ocpypl_id,lcpl_id)
H5O.copy(src_loc_id,src_name,dst_loc_id,dst_name,ocpypl_id,lcpl_id) copies
the group, dataset or named datatype specified by src_name from
the file or group specified by src_loc_id to the
destination location dst_loc_id.
The destination location, as specified in dst_loc_id,
may be a group in the current file or a location in a different file.
If dst_loc_id is a file identifier, the copy will
be placed in that file's root group.
The new copy will be created with the name dst_name. dst_name must
not pre-exist in the destination location. If dst_name already
exists at the location dst_loc_id, the operation
will fail.
The new copy of the object is created with the object creation
property and link creation property lists ocpypl_id and lcpl_id,
respectively.
Copy the group '/g3' and all its datasets
to a new group '/g3.5'.
