[Nexus] Migration from nexus API to hdf5 API

[Peterson, Peter]

I am looking to migrate a code from using the nexus API to directly using hdf5. Changing everything all at once is a ton of work. The ideas I've had so far for a more gradual migration:

  1.  Is there a way to check an NXhandle that it is to an hdf5 file and then use a member of the NXhandle directly with the hdf5 api?
  2.  Can one open the same file with hdf5 and nexus and carry around both handles at the same time? This would probably require using "reopen" and being careful about access to make it work.
  3.  Any other ideas?
