h5copy(ifile,ofile,srcObjName,dstObjName)

function h5copy(ifile,ofile,srcObjName,dstObjName)
%H5COPY recursively copies an object from one HDF5 file to another file.
%
%   h5copy(INPUTFILE,OUTPUTFILE,SRCOBJ,DSTOBJ) copies the source object 
%   name SRCOBJ in the input HDF5 file INPUTFILE to the destination 
%   identified by DSTOBJ in OUTPUTFILE.
%
%   The behavior of the copy is to recursively copy all objects below the 
%   group, keep soft links as they are, keep external links as they are, 
%   update only the values of object references, and to copy attributes 
%   along with the object.
