Trying to get the test_dForm.py to work.
The line failing in getStructureDescription is:
field_structure[field_name] = (field_type, False,
max(field_info[2],
field_info[3]) or None, field_info[5] or None)
The reason is that field_info[2] and field_info[3] contain None.
How to best correct this?

In Python 2:
>>> max(0, None)
0
In Python 3.4:
>>> max(0, None)

I was going to say we should use six to help the transition between 2
and 3 but see that six doesn't solve this issue for us.
You need to rewrite that to take into account None being a possible
value in [2] or [3] (order None as less than everything). That will be
cross compatible.
