[AstroPy] Image combine

I'm not aware of a function that does it exactly with the interface of
imcombine, but it can be done pretty easily with pyfits:

import pyfits

f1 = pyfits.open('filename1')
f2 = pyfits.open('filename2')

h1 = f1[0].header
im1 = f1[0].data
im2 = f2[0].data

newimage = im1 + im2

newhdu = pyfits.PrimaryHDU(data=newimage,header=h1)
newhdu.writeto('newfilename')


That example is specific to addition, of course (the im1 + im2 part,
but it should be clear how to generalize it to other arithmetic
operations.
