Python 3 division

[Hal Murray]

Several of our python modules don't import division from __future__
Maybe that's because they don't do any divides.  I think it would be simpler 
to always include division so we don't have to remember to see if we need to 
add it every time we a chunk of code that does a divide.

[murray at hgm raw]$ grep __future__ . -r | grep -v division
./pylib/agentx.py:from __future__ import print_function
./pylib/__init__.py:from __future__ import absolute_import  # Ensure Python2 
behaves like Python 3
./wscript:from __future__ import print_function
./tests/pylib/test_util.py:from __future__ import print_function
./ntpclients/ntploggps.py:from __future__ import print_function
