Python3 (again!)

[stevemolloy]

As I wrote for pyrpn, I was wondering if there was anything that prevented this being expanded to allow use with python3?
(As before, I'm more than willing to do the work myself if you don't see any major stumbling blocks.)

Compatibility could be resolved by using __future__ module, but the GUI does depend on wxPython, which requires some non-trivial work to make it run under Python 3.

The most recent version of wxPython is 4.0.0b2 (beta version), which supports Python 3, but there are some issues need to be fixed. I was working to upgrade another project (felapps) with this version of wx half years ago, there're lots of changes.

I created pull request #9 to have everything except the UI already transformed to Python 3 compatible code, as far as the tests and my daily usage showed.

Are you using the UI?

[smartsammler]

No, I did not manage to get wx working properly on my system (Fedora) when I tested it back then.
And from then on I used a version with the UI parts commented out.
I'll give wx a new try, because with the new version there are even wheels available.

After PR #13 being merged into master, Python 3.x would be fully supported, including UI (though not quite useful). pip install beamline --upgrade will install version 2.0.0, which requires wxpython 4.0.1 and Python 3.x.

@smartsammler I've put a file named install_deps.sh in the project directory, which is required before installing wxpython 4.0.1 via pip install, the package names in Fedora might be different.

Thanks. I'll test it when I'm back on my main system.
