Potential Python 3 function incompatibility for `calculate_alignment.py`

One of the functions required for align.calculate_alignment---dict.iteritems()---was deprecated in Python 3. After changing it to the new function---dict.items()---we get the following error:

[turn_real,convo_real] = align.calculate_alignment(
                            input_files=INPUT_FILES,
