Numpy: Python3 Support

[ax3l]

Hi @yyalli,

are you planning to add Python3 support for the numpy wrapper?

Thanks,
Axel

It sounds good to have python3 support. I will start working on this soon but it may take some time.

have you thought about maybe maintaining the wrapper in an independent repo (say github.com/ornladios/adios-python) and including the ADIOS C "main" library as a git submodule?
This would allow you to run continuous integration tests, e.g., with https://travis-ci.org that could make maintainance/testing way easier by running against various python and cython versions on the fly.

Just updated to support python3 (as well as python2). Only tested with python 3.5 and 2.7. It may need more tests. Anyway, I will appreciate if you can check and report any problem.

Tested with Debian 8 "Jessie" with Python 2.7 & 3.4 and serial adios.

• install: works
• open file: works
• reading variable via f["/ion__ExB_shear"][()] from utils/bpsplit/test/flow11.bp
  • ok in Python 2.7
  • segfault ok in Python 3

@yyalli since GitHub is your mainline, can I please get some feedback on continuous integration I proposed? I can even write you the files for travis-ci and it's free...

update: python 3 works, too. did not run setup.py clean before building it after python2 :)
