Fix typo in TemperatureFunctionTime.__call__ docstring
Added future division to utils, to prevent equivalence ratio errors.

In Python 2, integer division caused errors in the equivalence ratio
calculations in ``utils``. Adding the true division of Python 3 fixes
this.
Added future division to all modules for good measure
Fix typos in the docs
Merge pull request #33 from kyleniemeyer/master

Import future division for Python 2 compatibility
Merge branch 'multiple_inputs' of https://github.com/kyleniemeyer/CanSen into multiple_inputs
Remove whitespace at the end of the lines
Check if num_proc is None

Instead of relying on the truthiness of None, directly check for None
Change range(len()) to enumerate()
Check if a line in the input file is empty and ignore it
Write bytes to temp_file

Fixes Python 3 where string writing is no longer supported. Need to
check for regression in Python 2
Fix Python 3 function def doesn't allow tuple expansion

Tuples can't be expanded in function definitions in Python 3, so we have
to expand it in the function body.
Fix minor docs typo in run_cases.py
Fix Python 2/3 compatibility in the NamedTemporaryFile stuff
