The comment is asking for the error to be handled in the call to push.

To be clear, the desired behavior is:
If the group name is not present and createit is false, then the push call should throw an exception.

I don't feel right returning hid_t type outside hdf_archive which should hid details of the hdf5 library.
Example: hid_t should not appear in src/QMCWaveFunctions/RotatedSPOs.cpp
So I'm thinking of

1. push(name, createit). Throw an exception when creation is requested and failed or whgen creation is not requested and open group failed.
2. is_group can be used to inspect group existence.
3. if the group tid_t is actually needed use top() after a successful push().
