[AstroPy] iraf's imexamine equivalent in python

[Joe Philip Ninan]

Hi RayS,
Thanks for the suggestions.
I was so far trying to get ginga work from Ipython. (still stuck at some
error in PyQt4...)
I have never tried doing anything in wxPython before. But looks like I
should give a try on that also.
For 3d surface plot, I shall use Mayavi.
Thanking you,
-cheers
joe
