[Nexus-developers] NAPI Release

[Akeroyd, FA (Freddie)]

Paul,

Thanks for the additions - I've added them to the svn repository and
also re-opened #101 in case you have anything further to add. 

Ray was showing me your new high-level python interface during a visit a
few weeks ago. It look really useful and we will be discussing it at the
upcoming NIAC meeting.

Regards,

Freddie

I looked over the changes to the new python bindings and found a couple
of issues. I'm attaching a patch since trac won't let me post svn
changes without opening a ticket.  If someone reopens #101 I can post
against that.

The patch is large because there is a lot of whitespace changes, but a
couple of real bugs were fixed too.

I'm also attaching nexus.py + nxsunit.py, a high level nexus interface.
With it you can do things like:

     $ipython -pylab
     >> f3 = nexus.read('lrcs_3701.nxs')
     >> f3.Histogram1.instrument.monochromator.distance.nxdata_as('mm')
     -1100.100040435791
     >> f3.Historgram1.data.nxplot()

Data is only loaded when needed, and can be read using slabs.

Please test out the code and suggest interface changes or add it to the
distribution.

Thanks,

  - Paul
