astropy/docs/wcs/examples/from_file.py needs updating

[vtcloud]

Hi,
running the example in astropy/docs/wcs/examples/from_file.py throws me an value error:

    ValueError: When providing two arguments, the array must be of shape (N, 3)

on line 25. Changing the line from:

    pixcrd = numpy.array([[0, 0], [24, 38], [45, 98]], numpy.float_) 

->

    pixcrd = numpy.array([[0, 24, 45], [0, 38, 98]], numpy.float_)

solves the problem.

EDIT: Fixed formatting.

@vtcloud - Could you please provide more information (versions and full trace log)? The example works for me (astropy 1.2.1, numpy 1.11.2, python 3.4) as is and I'm not able to reproduce the error you're getting.
There wasn't any changes to the example itself for quite a while now, so I assume it should work for older astropy versions, too.
