[ITK Community] Support for different python versions

[Brian Helba]

Hi Michka,

In my own opinion, it's objectively quite unreasonable to support Python
2.5 at this point, and 2.4 should be absolutely out of consideration (it
doesn't even have the 'with' statement). Nevertheless, it all depends on
our users. We support C++ compilers that are older too (Python 2.5 was
released September 2006), but of course Python is free to upgrade.

I've found the general advice [1] on the Python site to be good, and it's
what I've followed when porting other code to Python 3 myself.

Best,
Brian
