A bit of work on portin the IO code to python 3
Got the ASCII test to pass
Added a tox setup and modified the travis-ci configuration to use tox.
Added language classifiers to setup.py to clarify supported versions (2.6, 2.7, 3.3)
Work on the travis-ci script to get it to install scipy/numpy before running the tests
Added tox install to travis script
Removed superfluous pip install in .travis.yml (tox does it), fixed capitalization in setup.py requirements
Configure tox to use system site packages (to not have to build numpy/scipy on travis-ci)
Setup travis to not use tox, to manage python versions and invoke nosetests by itself.
Merge branch 'toxify' of http://github.com/pacificclimate/pydap into develop
