Hello HDF5,

I am using hdf5 for all of my projects and its a great library!  
Specially in combination with xdmf and paraview it is wonderfull 🙂

To make the use of HDF5 much easier I would like to see a function like

h5LTopencreate\_group(...)  
&nbsp;&nbsp;(open a group or -if it does not exist-  
&nbsp;&nbsp;&nbsp;create that group and its parents)

to become part of HDF5-Lite.

What do you think?

Greetings  
Jens
