Saving EMData from Python

If you want to be prompted to supply a image name using a standard dialog use this approach 

   1 # save a single image
   2 a = test_image()
   3 from emsave import save_data
   4 save_data(a)
   5 
   6 # save a list of images as a stack
   7 b = test_image(2)
   8 save_data([a,b])
