PEP8 coding style

[aernan]

I would like to contribute to this project by making the code PEP8 compliant:
https://www.python.org/dev/peps/pep-0008/

I have never contributed to an open source project before so I'm hoping this is the right place to post and simple thing to start on.

This is the right place to post. It is fairly simple. But it generates a lot of changes - which makes it difficult to review. For starters, you will need to use this list of PEP8 requirements that are deliberately not met:

Check   Description             Justification
E111    req indent 4            Creates more continuation lines
E114    req indent 4 cmnt       Same
E231    req space after ,       makes calls like print() harder to read
E266    no ##                   Required by Doxygen
W291    trailing spaces in cmnt Needed for space preserving para reformat

I will push these as pep8.dat, and we'll see what it looks like then
