Transforming an EMData object

An EMData object may be transformed using the following syntax 

   1 e = EMData("mydata.hdf")
   2 t = Transform3D(EULER_EMAN,10,23,0) # three angles in the EMAN convention are az=10,alt=23,phi=0. The convention may also be EULER_SPIDER, EULER_IMAGIC, EULER_MRC, EULER_SPIN, EULER_XYZ
   3 t.set_pretrans(1,1,1)
   4 t.set_postrans(2,2,2)
   5 e.rotate_translate(t)
