[Nexus] 2D character arrays in python binding?

[Peterson, Peter F. (pf9)]

Carlos,

Thank you for the question. I'm do not know the answer, but I do know that
the python binding has been in a state of flux for some time. Please specify
which version of the NeXus API you are using and the path within the
installation of the binding.
