| const string | NAME = "rotational_iterative" |
The advantage of this over the 'regular' rotational alinger is that this is done in real space and does not use invariants.

To align 'this_img' with another image passed in through its parameters. The alignment uses a user-given comparison method to compare the two images. If none is given, a default one is used.
